This chapter is introducing the ten groups in five pairs of diseases, which are explained in earlier two chapters (19th and 20th chapters) of Sutra Sthana. The principal behind this grouping is the same as the billions of persons are clubbed only in three groups according to predominance of three dosha in their constitution and personality traits. Similarly, on the basis of curable/incurable, severity (mild/severe), origin (mental/physical), causative factors (endogenous/exogenous), and pathological sites of diseases (amashaya samuththa/pakwashaya samuththa, diseases can also be clubbed in five pairs of ten major groups.
The term roga may be applicable to both the doshas and diseases but there is difference between the two, in as much as doshas are numerable and diseases are innumerable. One dosha may be responsible for the causation of many diseases. As it is impossible to describe all the diseases in view of their innumerability, only ten groups will be explained here as are discovered by ancient sages.
After grouping of diseases, this chapter deals with grouping of other two aspects i.e. agni and patient. Agni (digestive ability) is of four types, tikshna agni (severe), mandaagni (low), vishamagni (irregular) and samaagni (balanced). Patients are of four types with the predominance of dosha - vatika, paittika, kaphaja and samaprakriti.
At the end of the chapter describes qualities of an expert physician who is perfect in diagnosis, skilled in treatment and has good knowledge of drugs.

Following are the two categories of diseases:
1. On the basis of Prognosis – i. Curables ii. Incurables 2. On the basis of Intensity - i. Mild ii. Severe 3.On the basis of Location - i. Physical ii. Mental 4.On the basis of Causes - i. Endogenous ii. Exogenous 5.On the basis of Origin - i. Digestive origin(Amashaya) ii. Excretory(pakwashaya) origin
Thus there are two categories of diseases based upon prognosis, intensity, location, cause and origin. There might be only one type of disease or many types of diseases based upon the classification (permutation and combination). Only one type of disease is based on similarity in causing pain and multiple types based upon ten categories and criteria mentioned above prognosis etc. That may be numerable or innumerable. Numerable as mentioned in the chapter Ashtodariya and innumerable as described in Maharoga Adhyaya owing to innumerability of nature of pain, change in colour, variation in origin etc. factors.

If something, already classified in a particular manner, is reclassified in another way following different criteria, there may be change in the number of groups, and such a charge should not render the statement suggesting such a classification incorrect.
An individual has the liberty to classify things as he likes. If something is already classified into some groups in a particular manner, he may reclassify it on the basis of different criteria which may result in changes in the number of groups in different ways. This does not invalidate the number of groups according to some other mode of classification. In some cases the criterion of classification may appear to be the same as the previous one but the specific features of each of these criteria should be observed in deciding about the validity of this classification. The same term may carry different meanings e.g. the word roga, antanka, yakshman, doshaprakriti and vikara (morbidity – these terms carry the meaning of or are synonymous with both dosha and vyadhi (disease). Thus the term roga is synonymous with both the dosha and vyadhi. For the rest like hetu (etiology) etc., this term, viz. roga carries a different meaning. 
Physical and psychic doshas and their vitiators

Because of their multitudinous nature, diseases are innumerable. On the other hand, doshas are numerable because of their limited number. So only some of the diseases will be explained by way of illustrations whereas doshas will be explained in their entirety. Rajas and tamas are the doshas pertaining to the mind and the types of morbidity caused by them are kama (passion), anger, greed, attachment, envy, ego, pride grief, worry, anxiety, fear, excitement etc. Vata, pitta and kapha- these three are the doshas pertaining to the body. Diseases caused by them are fever, diarrhea, edema, consumption, dyspnoea, meha (obstinate urinary disorder including diabetes), kushtha (obstinate skin disease including leprosy) etc. Thus doshas in their entirety and diseases in parts are explained.
Both of these types of doshas have three types of etiological factors, viz.
- unwholesome contact with the object of senses,
- intellectual errors, and
- seasonal vagaries. [5-6]
Factors responsible for manifestation of innumerable diseases

Depending upon the specific nature of the causative factors and also the specificity of the tissue elements afflicted, doshas when aggravated manifest innumerable types of diseases.

te ca vikArAH parasparamanuvartamAnAH kadAcidanubadhnanti kAmAdayo jvarAdayashca||8||
When allowed to persist for long, these psychic diseases viz. kama (passion) etc., and somatic diseases viz. fever etc., at times get combined with each other. 
Psychic doshas- their eternal union
नियतस्त्वनुबन्धो रजस्तमसोः परस्परं, न ह्यरजस्कं तमः प्रवर्तते ||९||
niyatastvanubandhō rajastamasōḥ parasparaṁ, na hyarajaskaṁ tamaḥ pravartatē ||9||
niyatastvanubandho rajastamasoH parasparaM, na hyarajaskaM tamaH pravartate ||9||
There is an eternal union between the two doshas pertaining to mind, viz. rajas and tamas. Tamas cannot manifest its actions without rajas. 
Combination of physical doshas

The three somatic doshas located at the same place and having identical attributes mostly combine with one another (samsarga) or with all taken together (sannipata). Attributes of doshas resemble those of the factors which vitiate those doshas. 
Primary and Secondary diseases

Characteristic features of primary and secondary (subordinate) diseases are as follows:
The primary disease manifests its own symptoms independently; this morbid condition is caused by factors specific to the manifestation of the disease. This can be cured by the therapies prescribed for that particular disease. The subordinate disease is characterized by opposite features. If all the three doshas are primarily vitiated at a time, the condition is known as sannipata. If only two of the doshas are vitiated, it is called samsarga. Depending upon the primary and subordinate nature of doshas, they are of many types. Considering such characteristic features, physicians attribute various names (like jwara or fever and atisara or diarrhea) to different conditions caused by doshas and diseases.

Depending upon their intensity, agnis (factors responsible for digestion and metabolism) located in the body of human beings can be classified under four categories, viz. tikshna (severe), manda (low), sama (normal) and vishama (irregular). The tikshna type is capable of tolerating all types of irregularities whereas the manda type is of opposite nature, i.e. even a small irregularity will impair its functioning. The sama or balanced type of agni gets impaired even by minor irregularities; it maintains its normalcy so long as there is no irregularity. The irregular type of agni, as opposed to sama or balanced type, sometimes gets impaired and sometime it does not get impaired by irregularities.
These four types of agni occur in the four types of individuals. In individuals having vata, pitta and kapha in their balanced and normal state, the agnis are regular or balanced. In the case of individuals having the dominance of vata constitution, due to the affliction of the site of agni by vata, their agnis are irregular. In the case of individuals having the dominance of pitta, the agnis are sharp. Similarly, in the case of individuals having the dominance of kapha in the constitution, the agnis are mild due to the affliction of the site of agni by kapha.

Some scholars hold the view that living beings cannot have a balanced state of vata, pitta and kapha in their body because they are accustomed to the intake of diets which are seldom balanced. Therefore, according to them some individuals have vata prakriti (vatika constitution), some have pitta prakriti (pattika constitution) and the rest have kapha prakriti (shlaishmika constitution). This is not correct because physicians take an individual to be healthy only when vata, pitta and kapha in his body are in a state of equilibrium and health represents the natural state of the body. It is with a view to maintaining good health that all types of treatments are prescribed. That state of the body is the most cherished one. Therefore, there are individuals having the balanced state of vata, pitta and kapha in their body.
The use of terms like vataprakriti, pittaprakriti and kaphaprakriti is not correct because in these types of constitutions, there is always a dominance of doshas in the bodies of individuals. Prakriti means a normal or natural state and there should not be any dominance of doshas in the bodies of such individuals. So such individuals as are having the dominance of one or the other doshas cannot be described to have the normal state of their body. Thus to use the correct term, they are vatala (having the dominance of vata), pittala (having the dominance of pitta) and shlesmala (having the dominance of kapha), and these do not indicate the normal state of their body.

Four types of regimens are prescribed for the benefit of these four categories of individuals. For an individual having the balance state of all doshas, all the regimens to be adopted by him should be of balanced type. When there is predominance of doshas, depending upon the nature of the doshas involved, it is useful to adopt such three regimens as would be in contradiction with these three predominating doshas till there is normalcy of agni. It is only after the normalcy of the agni is attained, balanced regimens should be adopted. Similarly, various therapies and other regimens should be administered to these four categories of individuals. We shall now explain them in detail.

Vatala (dominance of vata), pittala (dominance of pitta) and shleshmala (dominance of kapha)- these three are the morbid state in individuals, even though, according to another school of thought they represent the natural states of the body. Their characteristic features are as given below: - vatala, pittala and shleshmala types of individuals are more susceptible to vatika, pittika and shlaishmika diseases respectively and such diseases in the respective types of individual become very severe.

If vatala type of individual resorts to such things which are aggravators of vata, vata in his body gets aggravated immediately. This does not happen in case of remaining two doshas. The aggravated vata afflicts individuals by the manifestation of disease already described, resulting in the impairment of strength, complexion, happiness and longevity. The following therapies alleviate this dosha:
- Proper administration of oleation and fomentation;
- Mild purgative prepared by the addition of fat, hot things and substances having sweet, sour and saline tastes;
- Food having the ingredients of the above mentioned properties.
- Massage, poultices, bandages, kneading, effusion, bath, samvahana (pressing and massaging by hand), pressing, using means of terrifying, methods of surprising and making oneself to forget (bad memories)
- Use of wine and asavas (fermented drinks)
- Fats from different sources mixed with drugs having digestive, stimulant, carminative, vata alleviating and purgative properties- they may be boiled hundred and thousand times and be used for being administered in different ways, viz. internal use, massage, enema, etc., and
- Observance of enema regimens, its regulations and adopting comfort (in behavior and lifestyle) [15-16]

To sum up, in this chapter, groups of diseases based upon vata etc. prakriti types, non-contradiction of classified categories of diseases, similarity in dosha and roga, numbers of doshas, diseases with one type, causes of vitiation of dosha, description of agni, and means to stimulate it’s functions, vata etc. dominant types of persons and their management to maintain normalcy of dosha are described in details by sage Atreya. [20-22]
Tattva Vimarsha (Fundamental Principles)
- The grouping of diseases, patients and agni is framed for development of common modalities for diagnosis and treatment.
- Understanding the disease, the agni (digestive capacity) and prakriti (constitution) of a person is of prime importance for a physician to provide effective treatment.
- Comprehensive knowledge of a disease includes its prognosis(curable or incurable), severity(mild or severe), location(soma or psyche),causes(endogenous or exogenous) and site of origin (stomach/digestive or large intestine/excretory).
- If a person has predominant dosha and indulges in activities or food increasing that dosha then he will have abrupt onset of disease caused by aggravation of that dosha.
- A disease with known etiology, clinical features pointing to a diagnosis and indicated effective treatment is called anubandhya, on the other hand a disease with unknown etiology, variable clinical features and not effective treatment is called anubandha.
- Mental and physical disorders may start as such but later influence each other.
- Passion, anger, greed, attachment, envy, ego, worry, anxiety, fear, excitement etc. are due to psychic dosha, raja and tamas.
- Rajas is the initiator of all actions. Tamas cannot act without rajas.
- Agni( digestive processes) of a person shall be diagnosed as tikshna(severe), manda(low), sama(balanced) and vishama(irregular). The selection of diet and dose of medicine depends upon agni.
Vidhi Vimarsha (Applied Inferences)
Methods of disease classification
The word Vimana literally means measurement, so this section gives the physical as well pathological parameters for the measurement of various entities like dosha, dhatu, agni, srotas etc. In the present chapter method of classification of diseases is given on the basis of prognosis, severity, site of origin, cause and location. Physicians are directed to diagnose the disease as primary or secondary one on the basis of vitiated dosha and treatment given.
Primary (anubandhya) and secondary (anubandha) dosha
Primary dosha manifest their respective diseases when they are aggravated. On the other hand, the sub-ordinate dosha manifests their respective symptoms only when they are stimulated by the primary dosha. In other words, in view of their un-manifested symptoms, subordinate dosha, do not get aggravated by the factor responsible for their aggravation as mentioned in the texts nor do they get alleviated by the therapy prescribed specially for them. They get alleviated only when the therapy prescribed for primary dosha is administered. That is to say the aggravation and alleviation of subordinate dosha are affected by the causative factors and therapies, other than their own. This is because they share the attributes of the dosha, of primary nature to some extent. For example, in the autumn season pitta is vitiated primarily and kapha secondarily due to sour vipaka of water etc. This is because sour taste is responsible for the vitiation of both. For the treatment of primary dosha, viz. pitta, ghee boiled with bitter drugs is employed; bitter taste, by nature, alleviates the subordinate dosha, viz. kapha also. 'Anubandhya and, anubandha are the technical terms for primary and secondary diseases respectively known to scholar adapt in the medical science.
Role of prakriti
The term prakriti (meaning natural state) has different other meaning as well. Because of these two factors and with a view to specifying the intention, Acharya has used the term prakritisthanam along with vatapittashleshmana. In the case of an individual having the dominance of vata in his constitution, agni becomes irregular only when the sites of agni in his body are afflicted by vata and not otherwise. Similar is the explanation for the changes in the agni in individuals having the dominance of pitta and kapha in their constitution. The concept of prakriti is also described in the chapter in the context of disease. It is worth mentioning that the prakriti described in this chapter is in reference to the diseased state i.e. vikrita avastha. [verses 1-2]
Dosha pertaining to mind are given priority in the order of their description because they are comparatively smaller in number. [verses 5-6]
Determination of psychosomatic constitution, as well as disease susceptibility of an individual in population through genetic trait, is known as prakriti. Prakriti is a broad term that encompasses all the three genotype, phenotype as well as endophenotype. The concept of prakriti in Ayurveda is related to the bio-characteristic of an individual in healthy state and its vulnerability for particular diseases. According to Ayurveda, prakriti of an individual once determined at the time of fertilization remains unchanged throughout life though it is well influenced by environment. Role of environment in determination of prakriti during prenatal period is as important as postnatal period. Reviewing the human embryology, it can be postulated that the three primitive germinal layers namely ectoderm, mesoderm and endoderm can be correlated with vatika, paittika and kaphaja trait. According to Ayurveda at the time of fertilization the doshika prakriti is determined by the doshika predominance of shukra (sperm) and shonita (ovum) that represent the fastidious genetic alignment of chromosomes in sperm and ovum and decide the genetic trait of zygote. Robust research is being conducted to study the link between prakriti and genes.
In Nidana Sthana Chapter 4 (Prameha Nidana), Acharya says that the development of disease is multi-factorial and it depends upon both the virulence of pathogens (nidana) as well as host response (dushya). Response of the host can be quantified by using prakriti as a parameter. [verse 13]
Classification of various diseases on five parameters is described and then gives a generalized method for classification of disease on the basis of grief as a universal symptom. Here it is important to note that the term grief is used instead of pain to identify the disease. The word grief (dukha) signifies both mental as well as physical trouble. Thus more emphasis is given on the fact that both the component of a disease i.e. somatic and psychic should be equally treated for successful management. Description of the causative dosha for mental diseases and their relation with physical dosha is given. In the same context the psychosomatic diseases are described. Chronic somatic diseases cause psychological diseases and chronic psychological diseases leads to somatic diseases i.e. both are intermingled and have cause and effect relationship.
Role of agni
The relation between agni and disease process is essential to be understood. Impairment of agni is a cause of accumulation of various toxic products inside body leading to disease. Agni includes all processes of digestion and metabolism taking at gross level, tissue level, micro-cellular level. Hence it needs a special emphasis while treating a disease. Diagnosis of agni of a person is one of key factor in understanding disease.
The term sharireshu indicates that agni (factors or enzymes responsible for digestion and metabolism) residing all over the body. However, in subsequent elaboration, agni residing in the gastrointestinal tract is described because this agni regulates the aggravation or abatement of all the other agni [Cha.Sa.Chikitsa Sthana 15/39]. Agni belonging to regular or balanced category are the most beneficial for a healthy living; still agni belonging to the sharp category are given priority in the order of description because of their importance in as much as they are capable of tolerating all types of irregularities. Balanced (sama) condition of vata, pitta, and kapha during their natural states and when they are aggravated, accompanies regular or balanced agni.
The charts 1,2 and 3 shows various types of agni and its related processes in ayurvedic perspective.
Current scientific research supports this age-old tenet of medical wisdom. Walter Cannon in 1920, documented the physiological changes in body as a response to stressors through hormones called catecholamines. This was further researched by Hans Selye to pioneer the field of stress research. He described the close relation between body and mind with various articles on stress affecting humans biologically. Biofeedback is found effective in the treatment of various psycho-somatic disorders. Dean Ornish and his colleagues also worked upon the concept to integrate yoga, meditation for designing protocol for stress management in a medical center.
International classification of diseases and related health problems is a system that classifies disease on the basis of interpretation and comparison of mortality and morbidity data across globe.
Applied aspect for future research
- Scientific validation of term prakriti and standardization of doshika and manasa prakriti.
