Understanding of modern physiology has gone through several changes and through several stages of evolution, from the standpoint of health and its workings. At first, there used to be a static view of the individual and of specific functions of a body’s constituent organs and tissues. Gradually, it was realized that there was an integrative control mechanism through the nervous system and psychic influences could not be regarded as functioning separately from the body. A study of endocrine secretions led to discoveries of newer processes of physiologic and metabolic conditions having integrative chemical control on the body and subsequently, new light was thrown onto the cellular structure and function. And now it is known that the whole human physiology is an integrated process of interdependent components. The peculiar characteristic of the human body is its capability to modify its internal structure and function to cope up and adapt to changes in the external environment. This capability naturally involves a continuous maintenance of the body structure by means of periodic repair of an organ’s wear and tear and provision of a continuous supply of energy for maintaining the optimal temperature and keeping the various interdependent systems running, so as to help the organism react appropriately to environmental changes within and without the body. The following three systems are integral to every organism, big or small:
- The system of fluid-balance of the body (or, the water-balance system):- A specific fluid matrix is essential to fulfil the expression of life phenomena. This system maintains the specific consistency and structure of the fluid matrix under the stress of varying environmental factors.
- The system of agni:- Specific heat (agni) is necessary to digest and assimilate material from the environment, providing for the necessary energy to maintain body heat and the functioning of various organs and systems.
- The system (or concept) of vital force:- Vital force is essential for the purpose of evolution of organisms as well as their ability to do complex activities, which essentially characterize life and differentiate animate from inanimate entities.
This threefold system has been briefly described by Sushruta as shabda, archi, and jala santanavata meaning the “Organization of vital, thermal and fliud balance”. Within and outside the living body, we can classify all activities and functions grossly into three groups:
- Visarga (To nourish) - Nourishment is required for the birth, growth and development of living beings, as well as for the evolution of the universe and various objects. It is required for new creations as well as augmentation of existing structures and tissues, union, conjunction, synthesis, anabolism, impletion and various other phenomena that drive evolution.
- Adana (To consume)- Consumption implies depletion of existing structures and tissues, dissociation or disjunction, division, catabolism, desiccation, reduction, destruction and annihilation of existing structures. Finally, this also indicates death in case of living beings and dissolution of the universe.
- Vikshepa (To circulate or move)- For all the above functions, various movements are required which form the third group.
In the external world, these activities are performed by the group of pancha mahabhuta i.e. prithvi, apa, agni, vayu and akasha. These activities in the external world are guided and controlled by:
- Soma (The Moon - controls the activities of group i (Visarga) )
- Surya (The Sun or agni – controls the activities of group ii (Adana)) , and
- Anila (Wind or Air – controls the activities of group iii (Vikshepa)).
In the living body, these activities (nourishment, consumption, and circulation) are going on in a coordinated, systematic and controlled manner continuously. The body constituents that govern these activities are representatives of soma, surya, and anila respectively. These are also called doshas-
- kapha- represents moon in the body, and is responsible for the activities of Visarga.
- pitta - represents sun in the body, and is responsible for the activities of Adana, and
- vata - represents air in the body, and is responsible for the activities of group Vikshepa.
Collectively, these are called tridosha. Ayurveda studies and understands all the normal and abnormal activities in the human body in terms of the workings of the tridosha. This chapter mainly deals with the detailed account of vata, while it also mentions the nature of pitta and kapha.
In Ayurveda, the whole concept of integration of all the above governing factors (the threefold system/organization, etc) and the concept of physical constitution of a human being has been known for thousands of years. The tridosha form the general outline of that constitutional pattern or scheme, and all constructive, integrative, assimilative, recuperative and eliminative processes are studied in terms of the nature and working of the tridosha as an integrated whole. These concepts are all inclusive and form the basis of gaining a complete comprehension of the body-mind processes as a whole. Balanced tridosha leads to good health while its imbalance either quantitatively or qualitatively leads to a diseased state.
The tridosha, when vitiated, are considered as the intrinsic cause of the disease, and they either confer a predisposition to or actually cause morbidities.
Doshas are susceptible to imbalance and vitiation and in turn they vitiate other structural and functional elements of the body. They are also known as dhatus as they support the body in their state of equilibrium, which represents normalcy. The state of equilibrium of doshas i.e. samyata or arogata is a disease free state. On the contrary, a diseased state is due to a deviation from the state of equilibrium(A. Hr. Su. 1/20). The unbalanced doshas are also called malas when they start vitiating the body.
Further in this chapter, it becomes very evident that the functions of vata dosha correspond very much not only to the functions of nervous system but also to functions of any system concerned with regulation, signaling, conduction and control of any information or any system in our body.
If we observe the following processes of physiology:
- Transportation of the digested nutrients to all the tissues of the body for their renewal and replenishment, transportation of oxygen and waste products.
- Transport into the cell (either passive or active by some energy pumps or co transport etc.).
- Contraction of all muscles in the body (striated, non-striated and cardiac).
- Movement of joints.
- Retention of various products within the body and their timely removal or excretion.
- Division of cells.
- Occurrence of one event after another in synchronisation.
- Control and integration of occurrence of events only to the desired limit.
- Regulation of all events occurring in the body, including the regulation of hormone secretion (by negative or positive feedback) by various mechanisms either through electrical signals or through neuro-hormonal mechanisms within our body are all because of vata dosha as Ayurveda says that vata is the only dosha capable of causing movement (due to raja bāhulya) in our body.

The sages who were eager to know about the good and bad properties of vata dosha assembled at a place and framed the following questions for the purpose of discussion among themselves:
- What are the properties of vata ?
- What aggravates the vata dosha?
- What are its alleviating factors?
- How is the vata dosha ,which is unapproachable due to its ethereal and unsteady nature, aggravated and alleviated by its respective factors?
- What are the functions of aggravated and non aggravated vata dosha which is situated within the body and outside in the loka (universe)?

Kusha, the descendent of Sankruti, then spoke “roughness, lightness, coldness, instability, coarseness and nonsliminess are the six properties of vata.”

Listening to this, Kumarashira Bhardvaja spoke, “It is, as you have described Sir, these that are the gunas of vata. The habitual usage of substances with the above stated identical properties or indulging in activities bringing identical experiential effects brings about the aggravation of vata dosha as the dhatus are enhanced by the habitual usage of similar properties.

Kankayana, a physician from Bahlika then spoke “what you have said is correct, Sir. These are truly the vata aggravating factors. Those opposite to it are its alleviating factors, as the alleviating factors are the opposites of the aggravating factors of the dhatus” Listening to it, Badisha Dhamargava said “It is as you have said, Sir. These are the aggravating and alleviating factors of vata. We will now discuss how the non-material and unstable, and thus, the inaccessible vata is aggravated and alleviated. Vata aggravators are those which bring roughness, lightness, coldness, instability, coarseness, non–sliminess and hollowness within the body. The vata dosha gets shelter in such state of the body or its part and gets augmented, resulting in aggravation state. The alleviating factors are again those which bring about unctuousness, heaviness, heat, smoothness, softness, sliminess and compactness in the body. Vata does not get accommodation in such a kind of body and thus gets alleviated.

Hearing the scientific explanation of Badisha which was approved by the sages, Varyovida, the royal sage said “Sir, all that you have told is very true and free from any exception and misleading notion. The functions of both the bodily and the external vata, either normal or aggravated, moving within or outside the body will now be described after paying obeisance to lord Vayu, as has been perceived by us through our direct observation, inference and textual knowledge.
Vata in its normalcy maintains the whole body and its systems, working as prāna, udāna, samāna, and apāna. It is the initiator of all kinds of activities within the body, the controller and impellor of all mental functions, and the employer of all sensory faculties (helping in the enjoyment of their subjects). It joins the body tissues and brings compactness to the body, prompts speech, is the origin of touch and sound, is the root cause of auditory and tactile sense faculties, is the causative factor of joy and courage, stimulates the digestive fire, and helps in the absorption of the dośhās and ejection of the excretory products. Vata traverses all gross and subtle channels, moulds the embryo shape and is the indicator of continuity of life.
The bodily vata, when aggravated, afflicts the body with various kinds of diseases and deteriorates or diminishes the strength, complexion, happiness, and the life span of an individual. It perturbs the mind, disturbs the sense faculties, destroys, deforms or retains the embryo for longer periods, gives rise to fear, grief, attachment, humility, excessive delirium, and takes away life. The natural vayu moving in the universe conducts the following functions: it sustains the earth, kindles the fire, brings about compactness and the movement of the sun, moon, stars and planets, creates the clouds, brings the rain, flows the rivers, brings about the sprouting of plants and the maturity of flowers, plants and fruits, divides the seasons, defines and manifests the shape and size of the products of the panchamahabhutas, brings the growth and maturity of the grains, dries them, and brings about transformation everywhere. The aggravated vata moving in the outside world performs the following functions: it breaks the peak of the mountains, uproots the trees, disturbs the oceans, generates earthquakes, causes thunderstorm in the clouds, generates dew, thunder, dust, sand, fish, frog, serpents, alkaline water, blood, stones, perturbs the properties of the six seasons, blights the plants (or renders them non- productive), spreads epidemics, can remove the substances in existence, and can destroy all the four yugās by altering the cloud, sun, fire and wind.
Vata is indivisible and is like an eternal god with no origin. The existence and destruction of all the creatures and their happiness and grief depends on vata. It is the God of death, is the controller, regulator, and the lord of all creatures, Aditi (the first one), Vishvakarma (creator of the universe), is vishvarupa (omniform, or with innumerable forms), sarvaga (omni-pervading), the regulator of all actions and thoughts in the universe, is subtle, and is omnipresent. It is lord Vishnu and permeates the whole universe. Lord Vayu alone is God.

Listening to sage Varyovida, Marichi said- “Though what you have said is true, how is the above description about the qualities of vata applicable to the science of medicine, in the understanding and practical approach to medicine, since this symposium is related to the science of medicine?”.
The sage Varyovida replied, “If a physician doesn’t understand and realize the qualities of vata - which is so very powerful, rough, quick and possessing so much destructive power - how will he be able to forewarn a patient well in advance about its disastrous effects and how would he advise about the qualities of the normal vata which are beneficial for good health, improvement of strength and complexion, lustre, growth, attainment of knowledge and longevity?

After listening to Kapya, lord Punarvasu Atreya spoke, “All of you have dealt with the various aspects of the subject very well, only with the exception that any generalized statement on the topic has not been made. Actually, all the three doshas (i.e. vata, pitta and kapha) in their natural states help in keeping the individual’s sensory faculties normal while enhancing the strength, complexion, happiness and life span of an individual. Just as the proper accomplishment of virtuous deeds (dharma), wealth (artha) and desires (kāma) lead to freedom from the cycle of birth and death (mokśha), similarly the proper regulation of all these three leads to immense happiness in this world and beyond. On the other hand their vitiation or aggravation leads to undesirable and disastrous effects in the lives of creatures just like the three vitiated seasons. ”
All the sages agreed to and welcomed the explanation of lord Atreya.
Thus it is said – listening to the exposition of lord Ātreya, all the sages agreed to and lauded lord Atreya, just as the gods did on hearing lord Indra. [13-15]

The six qualities of vata, two types of causes (aggravating and relieving factors), several functions, and four aspects (related to normalcy and aggravation within the body and outside), as well as the functions of kapha and pitta, views of the sages and conclusion by lord Atreya – all of these has been explained in this chapter on the merits and demerits of vata. [16-17]

Thus ends the twelfth chapter of Sutra Sthana on the merits and demerits of vata, compounded by Agnivesha and redacted by Charak. Thus concludes the Nirdesha Chatushka.
Tattva Vimarsha (Fundamental Principles)
- Three doshas, vata, pitta and kapha in their natural state help in keeping the individual’s sensory faculties normal, nourish the strength, complexion, happiness and a long life span.
- Out of the three doshas, vata dosha is considered supreme because it regulates all functions in the body including movement of the other two doshas, such as the functions of any system concerned with regulation, signalling, conduction and control of any information or any system in our body.
- Qualities of vata guna of vata is classified into three types, viz. naisargika guna, prakrtika guna and bhautika guna:
- Cardinal features (Naisargika guna or pratyatma niyata guna) of vata dosha is sparsha (touch sensation). Along with this quality, vata possesses the qualities of ether (or the akasha mahabhuta) e.g, shabda (sound). Therefore vata possesses sparsha as well as shabda gunas as the process of combination, interrelationship (anyonyanu pravesha).
- The prakritika guna (constitutional property) of vata is raja guna , as it is told to be rajo bahulya.
- Bhautika means the quality derived from the mahabhutas. The bhautika gunas of vata dosha are ruksha (dryness), sheeta (coldness), laghu (lightness), sukshma (minuteness), chala (movement), vishada (clearness) and khara (roughness).
- Vata is non-material (avayavasamghatarahita) in nature which can also be termed as rarefied in nature and is anavasthita (unstable) too. These two properties are due to its bhautik muhushchari (constantly mobile) composition. Vata is composed of akasha and vayu predominantly.
- Agni is represented by pitta, which in its non-aggravated and aggravated form performs various good and bad functions including digestion or indigestion, vision or loss of vision, normality or abnormality of body heat and complexion, valour, fear, anger, joy, attachment, happiness and other such pairs of opposing qualities.
- Soma, the moon or the god of water, is represented by kapha in the body which in its normal and abnormal state performs good or bad activities or functions in our body, such as firmness or sturdiness of the body and looseness of the body, nourishment and leanness, enthusiasm and laziness, potency and impotency, wisdom and ignorance and similar other pair of qualities.
Vidhi Vimarsha (Applied Inferences)
Functions of normal vata
Vata possesses movement (gati) due to dominance of Vayu mahabhuta and Rajas guna in its basic composition. It caused division of body components due to its dividing function(vibhajati). Vata possesses the following 16 kala (functional properties) as described below.
Operational head of body systems and mechanisms (Vayustantrayantradhara)
Tantra (System) implies sharira here, meaning the whole of the body system. Yantra (organs) refer to parts of the tantra, such as joints. Vata is the basis of this tantra and yantra as it is the initiator and the regulator of the overall system as well as its constituent parts.
Vata is the one which monitors homeostasis between:
- Apparatus and operator,
- Cell and its constituents,
- Cell and tissue,
- Tissue and organ, and
- Organ and the system,
It maintains common homeostasis and regulation within the body.
Five functional types of vata (Prana-udana-samana-vyana-apan atma)
With the help of the five lieutenants of vata:
- Prana (predominance of akash)– propensity to assimilate
- Apana (predominance of prithvi)- propensity to eliminate, aversion and ejection
- Samana (predominance of agni)- analyzing the ability to assimilate and get eliminated i.e. sara (nourishing part) and kitta (waste products)
- Vyana (predominance of vayu)- circulation in body
- Udana (predominance of water) -functional utilization
Ayurvedic scholars study each of these types of vata in depth. In the aforementioned section, we have given a few examples for ease of understanding.
Initiation of all movements (pravartaka cheshtanam)
Or, the initiator of different types of (higher and lower, visible and invisible, motor and sensory) functions of vata. Some aspects of modern medical science may be utilized for the purposes of developing an understanding of the above stated functions of vata dosha and also other functions, which have been described in further parts of the verses stated below.
Control and initiation of functions of mind, sense and locomotor organs
The function "Niyanta Praneta cha manasa Sarvendriayanamudyojaka Sarvendriyarthanam abhivodha" can be observed as below:
- Employs the sense organs
- Carries the extrinsic object from the nature
- For conversion to the intrinsic subjects
- Then to the knowledge
- Controller and conductor of the manas (mind) with the help of Indriyartha – indriya – indriyaadhishthana – indriyadravya – indriyabuddhi
- Conversion of indriyartha into manoartha and then into the knowledge.
Vata is regarded as the carrier of objects to their sense faculties and is the direct cause of skin and tactile sensation, without which no other sense faculty can enjoy their recipients perception (Cha. Su. 11/38).
All the sensory faculties are felt and respond only when they are conducted from the sensory point to the brain and are interpreted there. This whole process needs stimulation of one point after another which can occur through some connections which may be occurring through various mechanisms.
Vata integrates all of these eleven indriyas and derives specific work by coordination. The following are mentioned as the functions of the Nervous system:
- Receiving the sensory information
- Integration of the information to determine the needed response
- Transmitting the motor impulses
Compactness of body by bringing them together (sandhanakara sharirasya)
Sandhana means bringing together. Similar to the alingan karma of kapha, (For example, laying bricks one after another) but vayu performs it differently through carrying the useful ingredients for building the structure of the body. Moving the particles closer or farther is the function of vata. It caused compactness in body components.
Creating and maintaining proper structure of body components (sarvasharira dhatu vyuhakara)
- Cyclic circulation of nourishing constituents of the body - where exactly they are required and carried constantly through their respective channels .
- Vyuhan is described as transportation of nutrients to the respective body constituents and specific arrangements of particles or molecules in that tissue.
Thus is creates and maintains proper structure of all body components.
Initiation of speech (pravartaka vachah)
Vata is the impeller of the speech. Speech has been considered as the distinctive feature of akasha mahabhuta but is included under the next mahabhuta of vayu ( Cha. Su. 1/28) and hence speech has also been considered due to vata dosha.
Presence of vayu is essential for the production of sound. Sound waves result from the alternate compression and decompression of air molecules. They originate from a vibrating object, much the same way as water waves travel over the surface of water.
Fundamental role in sound and touch perception(prakriti shabda sparshayoh-shrotra sparshanyormulam)
Vata being seated at twak (skin), originates and possesses all the senses simultaneously, specifically through touch and hearing (which can be attributed to akasha and vayu). Similarly vata has been held especially responsible for the formation of the structure of the ears, and hence vata has been held responsible as the root cause of auditory faculty. This could be so because sound always needs a medium to be conducted. The sound produced in our surroundings takes the help of air present in the atmosphere to get conducted.
Initiation of enthusiasm and exhilaration (Harsha-utsahayo yoni)
- Vayu is the origin of excitement and enthusiasm. Effortless performance is utsaha
- Attainment of the goal or objective is harsha or enthusiasm
Stimulation of digestion and metabolism (samirano agne)
- Vayu stimulates the conversion of metabolites in different parts of the body in the ductless or ductus glands delivered to digestive workshops when and where needed
- It controls various secretions required for digestion (pitta) and also makes available necessary amount of energy required for a conversion (ushma), pittoshma is described as the nature of agni in the living body.
Absorption of harmful products (Dosha samshoshanah)
Vayu dries up the excessive discharges and other watery compounds to formulate an integral organ, atom by atom and tissue by tissue.
Excretion (Kshepta bahirmalanam)
- The integral formation of needful atoms and organs require timely ejection of waste materials.
- This is also performed by vata at various places in the form of ahara mala, doshamala, indriya malaand dhatumala.
Division of gross and subtle channels of transportation and transformation (sthulanu strotasam bhetta)
Srotas are micro and macro channels in the body. Vayu carries and disintegrates the entrants according to the size of cell with requisite pressure through its property of sanghatabhedha (disintegration)
Normal shape and size in embryo-genesis (karta garbhakrutinam)
Initially unicellular microorganism called beeja grows into a full-grown multi-cellular organism by mitotic division of cells, attributed to vata dosha - vayur vibhajati means vata controls formation of various body parts and organs. Therefore deranged functions of vata can lead to congenital abnormalities.
Representing vitality and liveliness (ayusho anuvrutti pratyayabhuto)
By all the above sixteen listed and detailed kala or properties, vata maintains and supports life when in non - aggravated state, i.e. balanced state.
- Rapid and Prompt nature of vata dosha and thus early initiation of treatment –
The nature of vata dosha is rapid, transient and prompt in its consequences in causing and maintaining the health (or disease) in individuals. Its swift nature and power should thus be very well known to the physician so that he may educate the patient well in advance for the diagnosis of vatika disorders and their treatment. Failure to do so may result in the disorders converting into untreatable form.
