Nyāya is a leading school of classical Indian philosophy. It is pioneering in epistemology, metaphysics, and logic in particular for all the philosophies and world views of India. The word nyāya means “method of reasoning” and is often translated with the shorthand “logic.” Nyāya’s development as a school of philosophy includes dimensions of metaphysics, ethics, and philosophy of language.
The Nyāya Sūtras by Gautama Ṛṣi present the essence of classical Indian Nyāya. This course presents some of the most important debates and discussions among logicians and samples of the major views and arguments of the early school of Nyāya. These include a defense of the existence of the self, an argument that God must exist as creator, and a vindication of the reality of the world against Buddhist skeptics and idealists.
You need to understand what is the purpose of introspection. It is to improve your own spiritual life. You have come to spiritual life for yourself. If you want self-realization, then focus on yourself, not others. Others have their own karma to live.
