(b) Basic Principles of Āܰ岹

The term Āܰ岹 is a compound word made of two parts: ܲ means life or longevity, and veda denotes knowledge or science. Thus Āܰ岹 refers to the knowledge/science for life or longevity, which is a rational and naturalistic system of medical knowledge and practice (Filliozat 1966-1968, 477). Its purpose is to prolong life–it not only cures the sickness of people, but also prevents them from getting sick (Basham 1976, 21-22). It provides physicians with practical information for treating patients, as well as for advising people on proper ways to maintain health and to live long (as mentioned at the beginning of Section 2. 3). As Zysk (1996, 8) has stated: in many cultures of the world, having a long life is a criterion for being considered healthy. More importantly, longevity allows people more opportunity to achieve their goals or fulfil duties. In Indian culture, four goals (ܰṣārٳ) are known, as mentioned in the Caraka ṃh (ūٰٳԲ 1. 15): accomplishment of virtues (dharma), attainment of wealth (artha), fulfilment of desire (), and liberation from the world (ǰṣa). The achievement of these goals relies on having good health and a long life–that is, the science of longevity.

There are eight branches (ṣṭṅg) in Āyurvedic science, namely (Benner 2005, 3853; Mitra 1985, 22):

  1. ⲹ쾱ٲ (internal medicine),
  2. śⲹٲԳٰ or śⲹ-貹󲹰ṛk (general surgery),
  3. śⲹٲԳٰ or ūṅg쾱ٲ (dealing with diseases above the clavicle),
  4. ūٲ or grahatantra (relating to possession by supernatural beings),
  5. 첹ܳṛtⲹ첹 or 쾱ٲ (paediatrics),
  6. agadatantra or ṣaǻ󾱰첹śԲ or 岹ṃṣṭr (toxicology),
  7. ⲹԲ or Ჹ峦쾱ٲ (geriatrics and life prolongation), and
  8. ī첹ṇa or ṛṣ (pertaining to aphrodisiacs).[1]

Anatomical and physiological principles are important in Āܰ岹 for understanding physical health and disease (Weiss 2005, 715). The anatomical knowledge in the classical Āyurvedic texts is thought to come principally from Vedic sources, which contain long lists of body parts from dissecting animals during religious sacrificial rituals (Chopra 2003, 75). Anatomical data were also obtained from examination of bodies of the injured or killed. Dissection of human corpses, though a strong taboo in ancient India, was not unknown in early times (Basham 1976, 27-29).[2]

The fundamental physiological principles of Āܰ岹 include the theories of 貹ñūٲ, ṣa, ٳܲ, and malas. The doctrine of 貹ñūٲ forms the very basis of Āyurvedic science (Chopra 2003, 75). ٴṣa, ٳܲ, and malas are recognised in the classical Āyurvedic treatises as the “root� of the body (śܳٲ ṃh ūٰٳԲ 15. 3; Aṣṭāṅga ṛdⲹ ṃh ūٰٳԲ 11. 1). These concepts will be concisely introduced as follows.

ʲñūٲ (or simply 貹ñūٲ), the five great elements, are earth (ṛtī), water (ap), fire (tejas), wind or air (), and space (ś). These five are the elemental substances of all physical matter in the universe, including the human body. By adopting this ideology of the ṃkⲹ school, the Āyurvedic system holds that humans as microcosms of the universe can interact with nature (Chopra 2003, 75; Filliozat 1964, 26-27). Each of these five elements, according to the Āyurvedic (and other Indian philosophical) literature,[3] has its special qualities. Moreover, each predominates in certain bodily components and manifests certain functions.

Mitra (1985, 55) has extracted such information from a passage in one of the Āyuvedic texts (Caraka ṃh ŚīٳԲ 7.16) and given the translation as follows:

“Whatever is predominently [sic] gross (ٳū), firm or static (sthira), solid (ūپ), heavy (guru), rough (khara), and hard (첹ṻԲ) part of the body, viz., nails, bones, teeth, flesh, skin, faeces, hair of the head, face and body, tendons as well as odour and the sense of smell, belongs to ṛt󾱱ī ūٲ [sic]. Whatever is predominently [sic] liquid (drava), diffusive (sara), sluggish (manda), viscous (snigdha), soft (ṛd) and pasty (picchila), viz., body nutrient fluid (rasa), blood, fat, kapha [sic] or phlegm, pitta [sic] or bile, urine, sweat, etc., belongs to Ap ٳ. Whatever in the body is of the nature of Pitta, heat and radiating lustre () as well as colour and complexion is referable to tejas ٳ. Whatever in the body is of the nature of inhalation and exhalation, opening and closing the eyes, contraction and extension, movement, impelling and holding, etc., as well as touch and the sense of touch are referable to [sic]. Whatever in the body is of the nature of porosity (vivikta), utterance and the channels that are gross and minute, as well as sound and the sense of hearing, are referable to ś ٳ.�[4]

The three ṣa (ٰṣa) are wind (ٲ or ), bile (pitta), and phlegm (kapha, śṣm; : semha),[5] which are thought, like all matters in the world, to evolve from the 貹ñūٲ.[6] They are often rendered as “humours� because of the similarity of this theory to the Greek humoral theory of Hippocrates and Galen. The term ṣa can literally mean “vitiator�, from the root (to spoil or to corrupt). It is because when the ṣa are in balance or in proper proportion they lead to a good state of health; otherwise they can cause various diseases and even death. Although these humours carry a sense of negative implication, they are essential to all bodily functions.[7] They are thought to be semi-fluids circulating in the body via special channels, but each of them predominates in certain part of the body: ٲ in the lower abdomen, pitta in the upper abdomen, and kapha in the chest and head. They have their own qualities: ٲ is dry, cold, light, mobile, non-slimy, and coarse; pitta is greasy, hot, sour, pungent, sharp, and fluid; kapha is heavy, cold, viscous, soft, sweet, and slimy (as described in the Caraka ṃh ūٰٳԲ 1. 59-61, as well as in the Aṣṭāṅga ṛdⲹ ṃh ūٰٳԲ 1. 11-12).[8] The three ṣa have their individual functions. ٲ, as wind, mainly exerts its function characterised by “movement�, such as body/limb movement, mental activation, speech utterance, respiration, intestinal peristalsis, bowel evacuation, etc. Pitta is responsible for functions such as digestion, metabolism, body heat, as well as making the body soft and flexible. It also induces psychological activities such as understanding, intelligence and courage. Kapha makes the body firm, smooth and stable, lubricates the joints, and refreshes the sense organs (Benner 2005, 3854-3855; Chopra 2003, 77-78).[9] The three ṣa undergo fluctuation and each of them dominates at a different period during the daytime and night-time. Variations of the three also occur at different seasons and at different stages of life. Conditions–such as habitat, food, lifestyle, and so on–can have influences on the functions of the ṣa (Chopra 2003, 78; Thakar 1992, 383). The three ṣa are already present at the start of life for each person, until the end of life. Moreover, every person has his/her unique constitution of the ṣa at birth, forming his/her ṛt. This constitution determines the individual physical and psychological characteristics; it also influences pathogenesis of disease and hence the treatment (Chopra 2003, 77-78; Thakar 1992, 382-385). In brief, the three ṣa together regulate all phases and activities of growth, maintenance and decay. Their balance is responsible for health, and their imbalance for illness and death.[10]

The term ٳ, though literally means “constituent part� or “element�, represents certain body substance or tissue in Āyurvedic science. There are seven ٳܲ: chyle (rasa), blood (rakta), muscle (ṃs), fat (medas), bone (asthi), marrow (), and semen (śܰ). Each of these seven, according to the Āyurvedic physiology, is derived one by one from each other, starting from the ingested food. Food undergoes the process of digestion, which assumes a very significant role in Āܰ岹 and is regulated by ṣa. Food is digested–viewed as being “cooked� by “digestive fire� (ṻ岵Ծ)–and this results in chyle. Then chyle is transformed by bile into blood, blood into flesh, flesh into fat, fat into bone, bone into marrow, and marrow into semen (Aṣṭāṅga ṛdⲹ ṃh ūٰٳԲ 1. 13; Caraka ṃh ūٰٳԲ 28. 4, 侱쾱ٲٳԲ 15. 16; Chopra 2003, 76-77). Through this process of digestion and metabolism, the seven ٳܲ are sustained and restored (Thakar 1992, 384).[11] These ٳܲ have their specific functions: chyle supplies nu[12] trients, blood helps maintain life activities, meat covers the bones, fat provides lubrication, bones support the body, marrow fills the bone, and semen is responsible for reproduction (Aṣṭāṅga ṛdⲹ ṃh ūٰٳԲ 11. 4).[13]

Mala, another “root� of body, refers to any bodily excretion; among which urine, faeces, and sweat are the major ones. Other examples of wastes are earwax, tears, nasal discharge, and so on (Caraka ṃh 侱쾱ٲٳԲ 15. 18-20). Being the waste products of the process of metabolism, they are passed out of the body. According to the Aṣṭāṅga ṛdⲹ ṃh (ūٰٳԲ 11. 5), the malas have their functions: the faeces sustain the strength of the body, the urine eliminates the moisture, and sweat retains the moisture.

According to the teachings of the Āܰ岹, health is achieved by the balance of the ṣa, the ٳܲ and the malas; sickness occurs when one or more of them are out of balance (Thakar 1992, 377). ٴṣa play an important role because their change can vitiate the balance of ٳܲ and malas, and the ṣa can cause imbalance of the ٳܲ and/or the malas resulting in disease (Benner 2005, 3855; Zysk 1991, 29). Most of the diseases (and even death) are explained by the imbalance of one or more of the three ṣa. When there is “causative factor� (ԾԲ) acting on the ṣa, the balance of the ṣa can be upset with the increase or decrease of one or more of the ṣa, and this leads to various symptoms and diseases (Weiss 2005, 714; Zysk 1996, 1). Causative factors can be diet, time, seasonal change, habitat, lifestyle, conduct, physical and/or emotional stress, suppression of natural urges, effect of previous actions (karma),[14] and so on (śܳٲ ṃh ūٰٳԲ 21. 19-26; Filliozat 1964, 29; Weiss 2005, 714). If a ṣa is increased, it first accumulates at its dominant area and causes pathology there; if further increased it overspreads from its area, causing morbid features (symptoms and signs) at other parts of the body.[15] Thus, as Thakar (1992, 386) clearly summarises, disease is conditioned by ԾԲ (external aetiological factor), ṣa (internal physiological factor) and ūṣy (the body parts to be affected). In addition, sickness can also be due to , which is considered as a harmful product of improperly digested food. It can cause blockage of the channels through which ṣa and ٳܲ flow, and subsequently disturbs their normal circulation and leads to disease (Benner 2005, 3855).[16] Other external factors such as injuries, poisons, and supernatural beings are also recognised as disease-causing in Āܰ岹.[17]

In order to make a diagnosis of the patient’s illness, a six-fold examination (ṣaḍv Dz貹īṣ�) of the patient will be carried out: the physician uses the five senses to observe the symptoms and signs, together with the interrogation (of the patient’s complaints) to make diagnosis (śܳٲ ṃh ūٰٳԲ 10. 4-5). Then the diagnosis is made by the Āyurvedic physician (vaidya) in terms of five criteria (ԾԲ 貹ñ첹): aetiology (ԾԲ), prodromal features (ūū貹), clinical features (ū貹), therapeutic trial (ܱ貹śⲹ), and pathogenesis (پ) (Aṣṭāṅga ṛdⲹ ṃh ԲٳԲ (ԲٳԲ) 1. 2-8).[18] Apart from these, special diagnostic skills have been added and utilised in the long history of Āܰ岹, for instance: examination of urine (ūٰ貹īṣ�) came into practice from about the eleventh century Common Era; examination of the pulse (ḍīpīṣ�)[19] appeared in the Śārṅgadhara ṃh (circa the fourteenth century); examination of the eight bases (ṣṭٳԲ貹īṣ�)–which examines the patient’s pulse, urine, faeces, tongue, eyes, general appearance, voice, and skin–began to be used from the sixteenth century. Furthermore, prognostic methods were also developed in Āܰ岹. For example, a technique in which an oil-drop was placed on the surface of the patient’s urine, to determine his/her remaining lifespan, has been employed from about the sixteenth century (Wujastyk 1993, 767).

Āܰ岹 includes both therapeutic and preventive aspects. In respect to therapy, it employs many different measures such as medicinal substances, diet, emesis, enemas, purgation, massage, bloodletting, douches, sweating, surgery, and so on (Wujastyk 2005, 1411). The chief goal of various therapies in Āܰ岹 is to restore the balance–especially that of the ṣa. After diagnosing which humour or humours are increased or decreased, different drugs or treatments are prescribed to counter the pathogenic factor(s) and to correct the imbalance (Weiss 2005, 714).[20]

The materia medica recorded in the ancient Āyurvedic treatises is vast, containing various vegetal, animal and mineral substances with specific healing properties (Wujastyk 1993, 761). The body of medicinal substances was enlarging with new drugs being introduced, such as opium and metallic compounds (from the development of alchemy in the second millennium of the Common Era, especially for rejuvenation and extraordinary powers) (Chopra 2003, 80-81; Mazars 2006, 11-12).

Apart from using drugs, other modes of treatment were used. Five specific therapies (貹ñ첹rma) have been described in the early medical texts. For instance, in the Caraka ṃh these are emesis, purgation, oily enema, watery enema, and nasal catharsis (while the śܳٲ ṃh replaces one enema with bloodletting). Moreover, preparatory measures–such as consuming oil or applying oil externally (i.e. oiling), and causing sudation by various methods (i.e. sweating) in order to open the channels, mobilise the problematic humour/waste, and eliminate it–are often carried out before these treatments.[21]

Surgery was emphasised in the śܳٲ ṃh, but not in the other Āyurvedic texts. Various types of surgical techniques have been described in detail in this treatise, such as cataract couching, bone-setting, suturing, and so on. However, the practice of surgery seemed to have lost its importance very soon in the history of Āܰ岹, for there is almost no evidence of this practice in the historical sources of India in the medieval times (Wujastyk 1993, 763-765; 2005, 1411).

Apart from the above commonly employed remedies of Āܰ岹, there are other therapeutic measures. Dietetics has an important role in Āܰ岹. It is based on the doctrine that there is an association between taste (rasa) in foods and five mahāūٲs, and through such a principle that the six tastes–sweet, sour, salty, pungent, bitter, and astringent–assert different effects on the ṣa (Caraka ṃh ūٰٳԲ 1. 6466). Preparation and consumption of various foods and drinks are taught in Āܰ岹. In addition, a meat diet and alcohol sometimes are prescribed as medicines when necessary. [22] Another type of treatment is the magico-religious measures of the Vedic medicine. Some forms of Vedic medicine survive in the Āyurvedic medicine, though the latter is empirico-rational and emphasises on pharmaceutical/surgical cures. Magico-religious remedies such as ritual offering and spell chanting were used in Āܰ岹 for certain diseases, especially in the possessed conditions and paediatric diseases (Zysk 1991, 19-20).

Maintenance of health–for the purpose of long life–is another important aspect of Āܰ岹. There are many practical advices–what to do and what not to do–for this purpose according to Āܰ岹 (e.g. Aṣṭāṅga ṛdⲹ ṃh ūٰٳԲ 2-4), such as personal hygiene (tooth-brushing, bathing, cutting hairs and nails, etc.); non-suppression of natural urges (e.g. passing urine, faeces, flatus); suitability of and moderation in foods and drinks; physical exercises to control weight; time and place for sleep; ethical conduct (good deeds of body, speech and mind, e.g. no harming of other sentient beings, no stealing or robbing, no sexual misconduct, compassion, thinking of the benefits of others, etc.); appropriate occupations; suitable etiquettes and activities;good clothing and footwear; wearing talismans or amulets; usage of eye collyria, nasal drops, mouth gargles, etc.; body massage; regimens during different seasons; suitable living environment; and so on.

Karunadasa (2002, 392) points out that Buddhism (as well as Jainism) only recognises four great elements–earth, water, fire, wind–but not space (as the fifth mahāūٲ), even though space is sometimes listed with the four elements in the . Likewise, consciousness (ññṇa) is sometimes enumerated with the five items in discourses but it is not regarded as the sixth mahāūٲ. However, the Caraka ṃh (ŚīٳԲ 1. 16) groups the five great elements with consciousness (ٲ) and term them as six ٳܲ.

[4]:

There are many similar descriptions of the qualities and functions of these great elements found in the Āyurvedic treatises, and it is impossible to quote them all here. Mitra has composed a good chapter on the ūṭa, providing many references from Āyurvedic texts as well as Buddhist scriptures. See his book (1985, 40-56).

[5]:

ٲ, pitta and kapha are sometimes glossed as wind, fire, and water respectively, because of the properties of these elements in the ṣa (Benner 2005, 3854).

[6]:

Blood is sometimes listed as the fourth ṣa in some Āyurvedic texts. See, for example, śܳٲ ṃh ūٰٳԲ 21. 28.

[7]:

This general depiction of the three ṣa is based on information gathered from Basham 2004, 501; Benner 2005, 3854; Chopra 2003, 77; Thakar 1992, 382; and Wujastyk 2005, 1411.

[8]:

In the description of the Caraka ṃh, it also states that medicines having opposite qualities can relieve the qualities of these humours.

[9]:

Each ṣa is further divided into five kinds. Details of these kinds can be found in Aṣṭāṅga ṛdⲹ ṃh ūٰٳԲ 12. 4-18. See also Jolly 2012, 49-50.

[10]:

These three ṣa are commonly referred to in the Āyurvedic texts as pathogenic factors of physical body. Rajas (emotion) and tamas (darkness) are mentioned in the Caraka ṃh (ūٰٳԲ 1. 57) as the pathogenic factors of the mind causing vitiation of the mind. But these two are much less emphasised while discussing aetiology in Āܰ岹.

[11]:

The metabolic process, if functioning well, results in the production of ojas (rendered as energy or vitality, which is the essence of the seven ٳܲ) which serves as the support of life and gives strength, courage and immunity to the body; without it, life vanishes (Chopra 2003, 76; Jolly 2012,

[12]:

; Thakar 1992, 384). For more information on ojas (also known as bala in the śܳٲ ṃh), see Caraka ṃh ūٰٳԲ 30. 8-14; śܳٲ ṃh ūٰٳԲ 15. 19-28; Aṣṭāṅga ṛdⲹ ṃh ūٰٳԲ 11. 39-41.

[13]:

In the metabolic process, upaٳ (secondary ٳ) and mala (excretion) are also formed. Upaٳܲ refer to bodily tissues or fluids such as skin, hair, tendons, breast milk, menses etc., which are regarded as side-products of the ٳܲ (Caraka ṃh 侱쾱ٲٳԲ 15. 17). Malas will be described in the following paragraph.

[14]:

According to Zysk (1991, 30-31), the classical Āyurvedic texts have little regard for karma as a cause of illness, though it is listed as a theoretical cause. And it seems to have more importance in the area of embryology.

[15]:

Caraka ṃh (ūٰٳԲ 17. 114) and Aṣṭāṅga ṛdⲹ ṃh (ūٰٳԲ 12. 22-24) state two pathological stages for the ṣa: accumulation (caya) and aggravation (prakopa or kopa); śܳٲ ṃh (ūٰٳԲ 21. 18-37) describes six abnormal stages: accumulation (ṃcⲹ), aggravation (prakopa), spread (prasara), localisation (ٳԲṃſⲹ), manifestation (vyakti), and specification (bheda).

[16]:

According to Āܰ岹 (e.g. Aṣṭāṅga ṛdⲹ ṃh ٳٲٳԲ (ٳٲٳԲ) 6. 4-6), mind is transported via channels; blockage of the channels can also lead to mental illness such as insanity. Moreover, mental stress can aggravate the ṣa (the physical body), while dysfunction of ṣa (and channels) can lead to insanity and epilepsy (mental and neurological disorders), as Thakar (1992, 385) has commented.

[17]:

Supernatural causes (e.g. deities or demons) are usually accounted for psychiatric and paediatric problems.

[18]:

There are different diagnostic principles in Āܰ岹, such as the ten-fold examination mentioned in the Caraka ṃh (վԲٳԲ (վԲٳԲ) 8. 94), which includes: physical constitution (ṛt), morbid manifestations (ṛt), excellence of the ٳܲ (), compactness of the body (ṃhԲԲ), measurement of bodily parts (ṇa), suitability of food (ٳⲹ), mental strength (sattva), capacity for intake of food (śپ), physical capacity for exercise (vyāy峾śakti) and age (vayas).

[19]:

According to Chopra (2003, 79), the appearance of the examination of the pulse in Āܰ岹 was probably influenced by Chinese medicine or Arabic medicine. He also mentions that scholars have suggested the possible influence by Tantric yoga.

[20]:

However, it is known that in Āyurvedic practice this principle is not necessarily followed. Often treatment is given based on empirical data rather than on theory (Benner 2005, 3855; Chopra 2003, 80).
