The spiritual thought, in vast and vivid manner, propounded by the great Indian seers is called Darsana. At the same time Darsana also means 'vision of truth and reality.' Indian thinkers were mainly concerned with the fundamental questions of existence: what is real or reality? What is the real nature of human being. How has the world come to be? Is it created? If it is created then who is the creator. What is knowledge etc.. Basically all these questions and their answers are mere blend of all those contemporary concerns which couldn't be answered by this worldly people. Tarkabhasa, a text, presents a detail discussion on Nyaya theory. It is known as an elementary treatise, a key for the beginners of the Science of Nyaya. It is quiet evident that Tarkabh4a is written by Kegava Migra, as mentioned at the end of the text. It presents the subject matter in an easy language. The Tarkabhasa with the commentary of Govardhana and critical and explanatory notes of S.M. Paranjape was first published in 1894. In the present edition, the editor has given a brief introduction of the subject-matter and has put forward the useful notes of S.M. Paranjape along with the text so that the students and advanced scholars could refer to the notes directly while reading the text.
