“Vishnutatva Nirnaya” is published in Kannada & Sanskrit PDF Format.
This is the most important of all the Prakaranas written by Acharya Madhwa.
One of the attributes of Narayana is : “He is the One mainly delineated in all the scriptures”. He is the only one Supreme Being, who is beyond the finite world, characterized by both perishable and imperishable realities. This is another of his attributes. The third attribute is that he is a reality, void of all defects and full of all attributes.
First Chapter is very extensive and deals with subjects like the divine origin of Vedas, the permanence of Varnas, the reality of the world, etc. Acharya Madhwa defends his reality of duality of Jiva and Iswara, with all the three kinds of evidence:
Pratyaksha (directly perceived), Anumana (logic) and Agama (scriptural).
Acharya’s attack is frontal on Mayavada or philosophy of Illusion. The books is Ambrosia for the seekers of Madhwa Philosophy.
