Abstract
Schools of thought or darsanas of Hindu philosophy can be classified into two groups: theistic systems and non-theistic ones. For example, the two Nyaya and Vedanta schools are among the theistic systems, which have given arguments to prove the existence of God. Some of these arguments are corresponding to the Islamic and Western arguments for the existence of God, while some others have been presented concerning the Hindu doctrines and culture. At the same time, these arguments have been attacked and rejected by rival schools, some of which are considered as the theistic schools. The present paper is going to enumerate the most important arguments as well as their related criticisms and to draw an outline of the discussions for the Persian-language readers rather than to deal with a detailed examination, or to involve in the rejection or acceptance of the proofs.
