Important principles of diseases in this section of the ''Roga Chatushka'' (tetrad on diseases) have been described. The preceding chapter provided a broader explanation for the cause of innumerable diseases due to ''dosha'' vitiation as well as variations in characteristics like pain, sign, etiology, site of origin, site of manifestation, symptoms and nomenclature. However, only the most important diseases, probably prevalent at that time, have been classified in view of prescribing treatment. Classification of these known diseases, based on characteristics provided above, and coupled with a few more variables such as prognosis, chronicity, treatment etc. have been done at various places within the [[Charaka Samhita]]. On critically analyzing, we find that the diseases have been classified into groups having as few as one to as many as eight diseases each.Three disease groups of twenty types each have been classified at the end. It has been observed that the listing of groups by diseases has been done in a descending order - from those having eight diseases to one  - because there are no other groups that have greater than eight types of diseases within them, except for the three groups with twenty types. Hence, these outliers (with twenty types) have been enumerated at the end rather than in the beginning of the chapter. Even though there are eighteen types of obstinate skin diseases, only the seven most obstinate ones have been enumerated here.

The relationship between the ''doshas'' and endogenous diseases can be explained using the following analogy mentioned in this text:  just as no bird (under the Sun) can fly without casting a shadow, no endogenous disease (caused by the disturbance of the equilibrium of ''dhatus'') can occur without the vitiation of ''vata, pitta'' and ''kapha''. The exogenous diseases may or may not be caused due to a vitiated ''dosha'' but so far as their treatment is concerned, ''doshas'' need not be factored in. There is also a mention of exogenous and endogenous diseases coexisting together. Endogenous diseases are, at times, followed by the exogenous ones and vice-versa. While treating such conditions, one should start treatment on the basis of the secondary development and our understanding of the primary nature of the disease.
