Shastra

There are six Darshan Shastras called the six schools of philosophy. They are: (1) Poorv Mimansaby Sage Jaimini, (2) Nyay by Sage Gautam, (3) Vaisheshik by Sage Kanad, (4) Sankhya by Bhagwan Kapil, (5) Yog by Sage Patanjali, and (6) Uttar Mimansa (Brahm Sutra) by Bhagwan Ved Vyas. All the six Darshan Shastras are in sutra form.

There is an interesting link between the need to anchor sociologist's training with knowledge of Sanskrit and the observation that the Shastras are sociological because the latter are in Sanskrit.

The answers to both questions are found in the Shastras of the Sanatana Dharma.
