''Nyayasudha'' is known as Sri Jayateertha’s magnum opus and is the exhaustive and detailed commentary (Teeka is Sanskrit for commentary, hence he also known as ''Teekacharya'') of Sri Madhvacharya’s ''Anuvyakhyana'' which in turn itself is a commentary on Brahma Sutras by Veda Vyasa. Sri Jayateertha has brilliantly and, more importantly, sincerely captured the pithy statements of his master in a lucid and simple language. It is universally admitted in the Dvaita tradition that the depth and breadth of the philosophical ocean of Tatvavada can only be appreciated with the help of the Nyaya Sudha. In a very attractive and lucid style, Sri Jayatirtha not only presents and strongly defends almost all the important philosophical and [[epistemological]] issues from the Dvaita point of view, but also severely criticizes other major philosophical systems of India such as the Bauddha, Jaina, Nyaya-Vaisesika, Bhatta-Prabhakara Mimamsa, Advaita and Visishtadvaita. Thus, in the Dvaita tradition, the work is held in very high esteem and it is believed that scholarship in Dvaita Vedanta is incomplete without a thorough study of this monumental work.
