The structuration and functionality of the living structures can be discussed in terms of information and matter-related information, as this was defined above. The living structures are able to work themselves as structured/self-maintained/self-multiplicative/organized systems, but with distinct functions. From the analysis of the necessary functions of the living systems, the following characteristic features can be outlined:
(1)the living structures need to consume organic and non-organic matter structures from the external neighborhoods and to convert them in suitable components to maintain their structure and operability;
(2)the operability refers actually to an informational process/(process chain), which assures in a standard and typical mode (automatically and always the same), the functionality of the entire structures and/or of their parts;
(3)the living structures should dispose of a central stationary warehouse/pattern of information, which would contain the necessary information for the suitable reproduction/(re)structuration, either of the entire structure and of each parts of it;
(4)as the existence of living structures depends on the interaction with the surrounding reality, changing under various conditions, such structures should dispose of an informational system of communication/detection/decision, because: (i) they should adapt (so react and decide) their functions and even their structure (plasticity), according to the detected changes; (ii) the reaction of such a system should be selective (decisional, preferential–between at least two YES/NO Bit-type alternatives), according to the survival tasks.
3.1. The information Model of the Living Structures
A most simple living cell, either a prokaryotic (non distinguished specialized components inside) and eukaryotic cell, is the unit of living structures. This living unit works under the conditions stipulated by the items (1)–(4) described above. Differently from the living systems, the trivial (mon-living) matter is not differentiable in general in informational functions like that described above. In the artificial informational (like microelectronic) systems, the information is carried by the electrical species, i.e., electrons and holes (lack of valence electrons of some atoms in the foreigner atoms-diffused silicon lattice) [
20,
21], as YES/NO dual/bipolar opposite-type mobile elements. The basic operators in such systems are switching components, operating with YES/NO type elements/signals.
According to item (1), the maintenance of the cell existence is assured by the metabolic processes [
27], providing both the cell energy and the primary components of structuration/restructuration of the cell, which mainly are the organic components. The energy supplier is the adenosine triphosphate (ATP) synthetized during the catabolic/metabolic processes, which is broken down into adenosine diphosphate (ADP) and inorganic phosphate, in cytoplasm and mitochondrion (in eukaryotic cell), an organelle working similarly with the lung in human and sub-human organisms on the basis of oxygen-assisted reactions [
22,
28] (
Figure 1 left side). The concentration of ADP is determinant for a signal transmission (YES) concerning a lack of energetic material or NOT in the case when the concentration is sufficiently high. Therefore, such a balancing relation between the concentration of ATP and ADP is a suggestive example, showing how some sequential metabolic processes are informationally/automatically managed inside of the cells, in agreement with relation (1). The informational automatic/autonomic (“programmed”) system, managing the metabolic (matter-related) processes, can be therefore defined as the Maintenance Informational System (MIS), and the corresponding cell pathways of the associated reactions as metabolic circuits. The inflow of the metabolic circuit is represented by matter (foods, air, water) and the outflow by wastes and uric acid. The reproduction system assures the formation of a new cell, fulfilling the requirement (3) in the list discussed above. Such a process is defined as replication and starts by the split of a molecule of deoxyribonucleic acid (DNA) into the two strands by specialized enzymes and the reconstruction of two DNA molecules, so a new cell (daughter) from the original one (mother) is obtained. Such a process is represented schematically in
Figure 1, showing the replication starting with DNA split in the nucleus of an eukaryotic cell, working as a Genetic Transmission System (GTS), referred in this case to the elemental micro-structural cell level.
The informational system defined as Info-Genetic Generation (IGG), refers to the management of body development, according to the age or necessities of matter (re)generation/(re)structuration, and is represented by the activity of RNA (ribonucleic acid)/enzymes assisting the transcription/translation process of some DNA informational sequences to yield the proteins, which are the building blocks of the organism [
27], from cell to multicellular bodies (
Figure 1 left side). The eukaryotic cells compose the major range of the living structures, from plants to animals and human, while the prokaryotic cells, as ones of the most rudimentary organisms, are typical for bacteria. The transcription process is actually an info-communication between the nucleous DNA and RNA messenger (mRNA), allowing together with some amino acids molecules from the externally foods (9 types) and/or fabricated by the organism itself (11 types in human) to prepare a suitable sort of (differentiated) proteins according to the local needs, with the informational contribution/communication of the transfer RNA (tRNA) from ribosomes/nucleolus components of the cell [
22,
28].
From the physics/chemistry point of view, DNA is a very large molecule contained by chromosomes, which are composed by DNA (30-40%), RNA (ribonucleic acid, 1-10%) and histones (50-60%), some proteins which anchor the double helix type DNA structure to avoid its physical damage. The largest human chromosome with approximately 220 million base pairs (bp) measures 85 mm long if straightened [
29,
30,
31]. The proportion of these components is different by species, various tissues of the same organism, and even in the same cell, depending on the evolution stages of the cell life cycle and its specific functions/tasks. From informational point of view (rel. (1)), the informational ability/capability of the DNA molecule at micro-structural nucleic level, is revealed by the info-operability of its structure, which consists in two strands of carbon, bonded by bases (nucleotides), which are four distinct units, acting as informational “letters”: Adenine (A), Thymine (T), Cytosine (C) and Guanine (G), which accomplish the rule that A may bind only the complementary T base and C only the complementary base G, as a YES/NO informational (binary Bit-type) operator. The human DNA can contain hundreds of millions of pairs. The enormous number of possible combinations/permutations of such structural units (“letters”), allows the formation of a specific DNA informational “language”, and the certain sequences express/transmit actually to mRNA and finally to proteins the specific encoded information of a certain corresponding structuration. As DNA/RNA/proteins are specific structures for each type of organism, the estimation of the quantity of information in various eukaryotic cells [
32] exhibits the evolution and organism info-development on the evolutionary scale as follows: 5.07×10
6 Bits (Staphylococcus aureus (bacterium)); 1.08×10
8 Bits (Aegypti (mosquito)); 4.13×10
8 Bits (Gallus (chicken)); 5.28×10
8 Bits (Bos Taurus (cow)); 8.38×10
8 Bits (Homo sapiens (human)).
As it can be observed from the above presentation, the info-structuration process is carried by mRNA/tRNA from the (DNA) memory–the informational master/library of the cell, with the contributions of enzymes, working for the decrease of the activation energy of reactions and construction/reconstructions of the info-components of the cells. The GTS and IGG refer specifically to such matter-related information-associated processes, while MIS to the actual maintenance of the body structure. IGG and GTS work therefore for the further structuration and reproduction, while MIS for the present structuration and the energy provision. The system MIS+GTS+IGG can be defined as the Programmed Informational System, working automatically for any cell structure, assuring its existence, from its creation to its death.
The item (4) presented above stipulates however the necessity of communication/(inter)reaction with the external environment, depending on the momentary conditions, specially concerning the food (useful/necessary matter recourse) availability and the structure defense/sociability for survival and adaptation. Therefore, a primary condition consists in the capability of the elementary cell to perceive the concerned (selective) informational signals. This condition is fulfilled by means of info-receptors, situated on the cell membrane [
28]. These are structured by means of proteins, which recognize/bind only the complementary (YES/NO) type structures (ligands), so the reception is selective and memorized, because a certain type of information, according only to a certain type of structure, the same always, can be received (
Figure 1 left side).
A decisional YES/NO selection is operated as a function of the informational category. Therefore, a proto-knowledge of the external informational interaction is detected and selectively accepted or not, according to the momentary needs, so a Center of Acquirement and Storing of Information (CASI) and a Center of Decision and Command (CDC) could be defined, as a sum of the operative contributing components detecting and operating with momentary information. As the communication of the cell with the external environment is mutual, the cell itself transmits to the external neighborhood its own signals by means of specific output pores channels of the cell membrane. From this point of view, the cell membrane plays an essential role for the cell communication with the external environment, just because of the selective semi-transparency of such a membrane.
In the multicellular organisms [
28]
, the external communication is accomplished by direct contact, junction gap (like in the nervous system) or by means of hormones, which support a long-range communication [
27]
. As it was shown earlier [
22,
28]
, the eukaryotic cells (particularly a cell of a plant) uses a tubular wire-type structure (believed till recently to only support passively the cell), able to transport moreover the external environmental information from membrane to the cell nucleus, involving for this ionic and charge free electron/proton gradients near membrane and transmembrane proteins [
33]
, describable in terms of information theory [
23,
34]
.
IC in
Figure 1 is defined as the Info-Connection system, allowing the automatic selection of information according to the survival/inherited and acquired/”learned” requirements, which is manifested for instance in bacteria by the synchronized organization in colonies [
22,
28], at the migratory birds to recognize the flight trajectory at large distances, and for each particular species/cell to select from environment the specific signal and to decode/interpret its significance according to the inherited/acquired life experience/tasks and endowed informational tools.
According to the discussion on the reactivity of interacting components of a system, it is necessary to define an Info-Reactive Sentient System (IRSS), managing the sensitive reactive information in own body to an initial received signal, equivalent with the reaction interpreted in the human organism as “emotion”. The sum of CASI+CDC+IRSS, together with IC selective center compose the Operative Informational System, necessary for the momentary adaptive process.
A longer process of adaptation, attaining even the stable informational system (PIS), but without to change the genetic characteristics of species, is operated by epigenetic mechanisms, suggestively indicated by the vertical arrow in the central side of
Figure 1. The epigenetic mechanisms represent a pattern “patented” by nature to absorb information from environment and to integrate it into the living structures, as it is actually demonstrated by the informational relation (1). These play an efficient and proactive role to gain in organization/information on the evolutionary scale of the living structures. In terms of information, the epigenetic mechanisms could be discussed taking into account three main categories of signals [
29,
30,
31] and internal cell cascade-type reactions, named as: (i) “epigenetor”, which initiates the info-interaction with the environment, inducing a molecular reaction chain of interaction with the body cell; (ii) the “initiator” signal is triggered by epigenetor into the body cell, which have to be sufficiently intensive or insistent to induce the epigenetic process itself; (iii) the “maintainer” is the informational signal which conserves the epigenetic changes (represented mainly by DNA methylation, histone modifications and variants of nucleosome positioning, chromosome coating with (long) noncoding RNAs and others), transgenerationally transmitted. According to the informational model described here, such mechanisms could act on the informational system of the cell, even if an epigenetic final process is not actually attained, emphasizing the dynamics of info-operability of the cell, as a response of the informational stimulus.
The structuration of the solid bodies is based on the repetitive bonding-type association between atoms or molecules, the smallest microstructural elements which still maintain the properties of the entire material, resulting a repetitive lattice in the crystalline materials like silicon, the basic material in the microelectronic/microsystems devices. In the living organisms, the eukaryotic cell is the basic elementary unit of the multicellular organisms, much more complex than the simple molecules, composed by organelles inside of the eukaryotic cell bulk, protected by the external semitransparent membrane, which allows the inter-change with the external environment of matter and information by means of pores and surface receptors, specialized to receive only a specific information on the basis of complementarity with info-chemical agents (ligands) [
27], with a binary YES/NO type of communication. Surprisingly, but coherently, the eukaryotic cell shows similar functional properties, supported by organelles, like the human’s organs [
28,
35]. Indeed, the metabolic processes are managed by MIS, automatically running specific chemical reactions on the corresponding internal pathways in the cytoplasm body: vacuoles, which work like the stomach, the mitochondria organelles (containing their own DNA as process info-manager [
27] like the “lung” to produce energy from glucose in interaction with oxygen, the Golgi apparatus like a “heart” and blood vessels distributer of fluids in the cell body, the endoplasmic reticulum and lysosomes for lipid (fats) and insulin metabolism like the pancreas and spleen, for degradation of obsolete products in human and animals. The role of GTS and IGG is evidently played by multiplication–replication mechanism and by transcription-translation processes respectively. The plant cells have an additional organelle–chloroplast, for the preparation of glucose components directly, within a light-assisted processes involving chlorophyll participation [
34]. The functionality of the prokaryotic cells (bacterium), the most inferior organisms, is similar with that of the eukaryotic cell, but without distinctive organelles.
According to the above discussion, an Informational System of the Living Structures (ISLS) can be defined therefore by the following relation:
The revolutionary findings presented above, shows that the living organisms are bipolar structures, working with matter and information (
Figure 1), organized in seven informational systems, allowing the operation of matter for maintenance, reproduction and self-development by PIS, and assuring the momentary adaptation to the environmental conditions by means of OIS. This model is defined as the Informational Model of the Living Structures (IMLS).
As described above, the living structures are able to assure the long-time adaptation by means of epigenetic/”learning” processes, allowing the gradual integration of information in the self-core (DNA) structure and transgenerational transmission to the next generation. The living structures works like an informational “device” to assure the existence of the species by means of the info-genetic input (IGG) and output (GTS), and for momentary life adaptation by means of the info-input (CASI) and info-output (CDC). According to the above discussion, it is reasonable/justifiable to admit that the functions of the organism are the result of the intimate informational processes in the body, the “hardware” support of the beings’ behavior, while the informational system acts as an associated “software” for maintenance/species proliferation and adaptation, coherently/reactively communicating with the external environment.
3.2. The Informational Model of the Human Body
While the solid lifeless bodies are structured by the bonds between the atoms of the same chemical elements or by a few elements, the living bodies are structured by living cells as unit basic components, built basically with organic elements composed by atoms of carbon (the fundamental element of the living matter), hydrogen, oxygen, nitrogen and phosphorus, interconnecting between them in an aqueous fluid which transports the nutrients and information to the cells. In opposition with the solid bodies, in particular that of silicon–the basic material in the microelectronic technology [
20,
21], with stable bonding structure at normal temperature, the organic components of the living organisms can be stable, forming the rigid structure of the organism, but also consisting in various unstable mobile agents under a dynamic inter-changing state, carrying information between various macro-components of the body [
28,
35]. Following such a line of structuration, the compartmentalization process (specialization in organs by functions) is a “patented” strategy of nature, in order to decrease the entropy (assimilated with matter disorganization) in the living structures, by absorption and integration of information (increasing the organizing degree) on the evolutionary scale [
35,
36,
37]. Within the multicellular organisms, which are associative collectivities of elementary eukaryotic cells, these cells remain the main basic micro-structural components acting themselves as active organisms–living their own life, able to sustain themselves their own organization and functionality, but in the same time supporting the functionality of the entire body by differentiation in organs, according to the body requirements and necessities, as distinct entity, which must face as a whole the interface with environment and with own organization/functional problems. At human and subhuman organisms (animals), the brain centralizes the informational management of the body. As it can be seen from
Figure 1, the Informational System of the Human Body (ISHB) can be defined according to the above discussion, managed by the brain and connected to the body organs (transducers) which works as execution (but sensitive) elements (EE) (informed matter).
Besides some basic non-organic minerals, like Ca (useful to structure the rigid skeleton at human and animals, and electric conduction channels in plants [
33,
34]), Na and K (essential for the operability of the neurons at human and animals [
38]) and other elements, the organic eukaryotic cells form actually the body and tissues strucure of the multicellular organisms. In human, the informational circuits composed essentially by neurons are marked in
Figure 1 right side by dotted lines, connecting the specific brain areas responsible for the corresponding activity (CASI, CDC, IES, MIS, GTS, IGG, IC) with the body itself [
36,
37]. Distinctly from other organisms (although not really necessary), the human interprets the informational reactive sentient signals as emotions, so in this case we can redefine IRSS as Info-Emotional System (IES), such that it is schematically represented in
Figure 1 (central side) as a component IES of ISHB. The ISHB can be therefore defined by the following relation:
administrating the information in the entire organism.
The info-circuits corresponding to the informational systems defined above can be described as follows (
Figure 1 central and right side).
CASI is connected with the external and internal informational sensors and is supported by the sum of all brain areas where the internal and external information is received and stored, basically represented by short-term (1min.) memory connected to the prefrontal cortex, and by long-term memory connected to the hippocampus and cerebellum, the last one responsible for learned behaviors and acquired skills (like playing an instrument, driving a car), to thalamus–with the function of a relay for sensory impulses, and cerebral cortex for interpreting the main sensorial signals like touch, vision and hearing.
CDC is responsible for the main dynamic/operational abilities of the mind like thought, language/communication, comprehension, arithmetic and writing activites (especially supported by the left hemisphere), creativity, spatial ability, artistic and musical skills (especially supported by the right hemisphere), intelligence, motivation, judgement, planning, voluntary control/command of muscles (EE), operated by the cerebral hemispheres, frontal and prefrontal lobes of the cerebrum for the acquired skills.
IES manages the emotions and sensorial impulses by means of the limbic system, composed by thalamus, hypothalamus, hippocampus, midbrain and amygdala (info-alarm component) and is connected especially to the hearth, which administrates the blood distribution to the action involved regions as motor-impulsive reaction to the input information.
MIS operates automatically the metabolic circuit, to manage by means of the brain stem as a relay between cerebrum, cerebellum and spinal cord and medulla the operational processes related to the digestion and the distribution in the organism of the necessary nutrients (breathing, heart rate, body temperature, wake and sleep cycles and digestion, reflex functions like cardiac activity–the rate and force of heartbeat, vasomotor regulation, variation of diameter of the blood vessels and the blood pressure), so is connected to the digestive and the cardio-respiratory system/organs of the body, while the hypothalamus controls and integrates the activities of the autonomic nervous system as part also of MIS.
GTS is correlated mainly with hypophysis and hypothalamus, responsible for the sexual activity. This system assures the output matter-related (genetic) information of the body, including the epigenetically acquired traits.
IGG is the informational genetic generator of the body, transferring the information from the parents to the offspring, managing the development of the body according to the age, especially by means of hypophysis and hypothalamus to regulate the body growth and its development. The basal ganglia are also involved in the personality features. The immune system, a complex organization of mobile cells, fighting against the local micro-organisms investors, and stable organs (thymus, spleen, lymph vessels and nodes), is managed also by the hypophysis/hypothalamus axis, involving an intensive and precise micro/macro informational activity between cells spread in the entire human/mammals’ body themselves and brain, exhibiting a relevant example of info-coordination/info-communication on the tridimensional (3D) map of the organism [
39,
40].
IC is the info-connection system supported by the anterior cingulate cortex, which is a brain structure between cortex and the other inferior structures, automatically acting as a hub for the selective (criterial) transmission of information to the prefrontal lobes (conscious, judgment area), as it was recently discussed [
12,
35,
37].
IC is center/system scrutinizing/detecting the certainty vs. uncertainty during the exploration of reality, advertising on a non-right (NO) vs. right (YES) interpretation of information on the connected range of information among the entire spectrum, comparing automatically the new information with the GOOD/trust/verified/FIABLE inherited/acquired information, which represent the life experience. For understanding better the IC role, a special attention should be paid to the studies on anterior cingulate cortex (ACC) at human and animals [
41], showing that ACC lies/complies in/with a special and unique position/task between the limbic system, which manages/interprets/selects information including info-emotions (IES), to be transmitted to the prefrontal cortex (CASI) and judgment (CDC), and which signalizes a “wrong” info-interpretation with respect to the info-references from memory (CASI). The electroencephalographic (EEG) studies have been showing that ACC produces ‘‘distress signals’’ upon the detection of errors, conflict, and expectancy violation, called the error-related negativity (ERN). ACC plays actually not only a role of a hub of info-distribution from the inferior zones of the brain to the decisional prefrontal cortex, but also that of an interpreter of information with respect to a reference value (criterion), and let pass normally the non-error/certainty information, in agreement with the correct functionality of the body and its interaction with reality, so with the individual/species “norms”/tasks, really checked/verified/accepted as “GOOD”/right, while the “BAD”/uncertain information is selected as a “distress” signal for life and survival. By “norms”, this should be understand both as the inherited and adopted/acquired decision criteria included/represented by mentality, as a complex set of rules/”instructions” set, learned in family/school/society. ACC is therefore an YES/NO administrator of (GOOD/BAD) information before to enter in the judgement (CASI/CDC) circuit, with the participation of IES/CASI (limbic system), serving for the correct/right orientation/“navigation” in the life. These findings were demonstrated recently in rats, showing that ACC sustains attention to a goal with accuracy and performance of the judgement [
43].
At human, IC is involved in trustworthy-related states, in any forms of scrutinizing the future events and situations, developing/(expressed by) premonition and other extra-sensorial phenomena [
44], in particular the extra-corporal detection of reality during NDEs experiences [
45] and even in extra-consciousness after the body death, clinically proved [
45], as well as in certainty/trustworthy states emulated by the Religious and Mystic Experiences (RMEs) [
46]. The activity of the posterior cingulate cortex was recently clarified [
47], and consists in the automatic disconnection from the external reality and connection (by means of the mind “eyes”–the prefrontal cortex) to the internal world, for analysis according to own criteria and projections to an imaginary reality and personal dreaming plans for the future. This is also associated with the need of certainty and reliable “navigation” between the uncertain events of the life, so PCC is also a supporting part of IC.
Such a description allows to define the Informational System of the Human Body (IMHB) in terms of information, as presented above. The great importance of ISHB and ISLS is that they practically show the similar informational structuration of the living organisms, from micro to macro organization scale, and the compatible association and communication in the colonies and multicellular bodies. Therefore, an Informational System of the Human Body and Living Structures (ISHBLS) can be defined, as following:
Relation (4) reveals the basic common informational composition of the living structures, as a fundamental property demonstrated by the Informational Model of the Human Body and Living Structures (IMHBLS) discussed here, on the entire biologic scale of organization, from micro to macro multicellular structuration.
As a living body is structured by the intervention of information within the biologic/physics/chemistry rules (deoxyribonucleic acid (DNA)-assisted processes and info-communication by electrical (nervous) and chemical (neurotransmitters, hormones, ligands) agents [
27], such processes are manifested finally as a direct “media-like” info-integrated product of mind, consisting in a conscious detection composing actually consciousness, on the “screen/display” of prefrontal cortex. The mind is therefore a tooling “device” of the body, resulted from own informational activity, outlining the informational panorama itself as a “mirror” reflection/projection of the detected/interpreted reality, recomposed by the informational system of the body, and expressed by the capacity of every individual to have access to the integral data “field” of his/her own life experience, where the thought acts as an informational operator, which can activate in every moment the required information from internal/external reality panorama. Consciousness is the resulted info-representation of the explored reality, acquired by the momentary connection and compared/combined with the life experience and interpreted (“decoded”) conformingly, serving as judgment reference/criteria. There are various forms and capacity of knowledge (“consciousness”) for exploration of reality in the living world, specific to each species, depending on the sensorial and info-processing “tools” which each species/exemplar is endowed with, and on the complexity degree on the evolution/organization scale, even some of them do not dispose of a nervous system, like plants and bacteria, as it is presented in the next section in more details. In other words, the integral physical (matter-related) panorama of reality, received/perceived through the (limited) informational “window” as an informational input in the living structures, in particular at human and subhuman organisms, is finally “objectified”/converted/transduced/”reduced” by the body informational system and associated tools/micro-macro devices, to a pure (non-physical) informational impressing/”imprinted” result, as an informational internal projected panorama, submitted to analysis/interpretation (decoding), judgment and decision, which becomes own virtual informational “reality”.
Consciousness in human, defined within the Informational Model of Consciousness (IMC), as a part of IMHBLS, more complex and distinguished from other subhuman categories, and improved by language as a communication tool [
48], is therefore a result of the projection of the informational activities of the ISHB on mind, as follows: CASI => Iknow (memory), CDC => Iwant (decision), IES => Ilove (emotions–expressed by love, this representative driving force of life), MIS => Iam (self-detection/self-existence, power/health), GTS => Icreate (genetic transmission, self-creativity, associativity), IGG => Icreated (inherited features/traits/predispositions), IC => Ibelieve (beliefs, decision criteria), which are the cognitive centers of consciousness. Therefore, the own personality (I–the Ego), can be expressed as the following sum contributions:
Within the Informational Model of Consciousness (IMC), as described above, “I’ represents a personal reflection of reality, according not only to the personal capabilities and accuracy of reality detection by means of own sensors, but also to the personal ability/intelligence to operate with the received information on the basis of the accumulated life experience, mentality and decision criteria. Therefore, consciousness is always different not only from one person to another (I
A ≠ I
B in
Figure 1 right side), but also from a period of life to another at the same person. The contribution of each component to a decision Iwant, which is actually the informational output with respect to an objective analysis, i.e., the attitude, can be also different, depending on the proposed/analyzed/perceived object/objective [
49,
50].
In terms of information, the human body (like that of all the other living structures), can be regarded as an informational decisional “device”, allowing to receive and codify the information detected from reality, to transmit it by the body channels and to decoding it in the mind by consciousness. In philosophic terms, compared with ancient concepts and views, this informational model unifies the eastern and western concepts/models on the world and mind, explaining the energetic Yung/Yin Chinese contrarians by YES/NO–informational Bit type behavior, the Plato’s ideas/”forms” by “information” concept as participating components of reality, Aristotle’s materialist view with matter structuration, but assisted by information, and the archaic model of the seven “chakras” at human, as vital centers [
14].
