Other Great Associates of Madhwacarya:

Sripad Visnu Tirtha
This is the younger brother of Madhwa who became the founder of Sode Mutt. He was an incredible yogi and renunciate, living in a cave no wider than his body standing. In the pastime at Kanvatirtha some of his qualities are recorded in Madhwa Vijay. Tradition has it that to this day he is still performing austerities on the Kumara Hill at Subrahmanya Ksetra of the western Ghats. Hrsikesa Tirtha, in his book Sampradaya Paddhati, states that in the Kali Yuga Visnu Tirtha will re-appear to preach Madhwa philosophy there. His only known work is a book on the duties of 'sannyasa', including the importance of 'Visnu-bhakti', roles of 'grhasta' and 'sannyasa ashramas', and cleanliness, bathing, 'tilak', 'japa' (regulated chanting), worship of Deities, offering foods to the Lord, fasting, and vows taken during the four months of the rainy season etc.

Sripad Visnu Tirtha was given beautiful Deities of Bhu-Varaha by Sripad Madhwacarya. Lord Varaha is very nicely decorated with Bhudevi seated on His left thigh. Incidently at the Sode Mutt they also have a Deity of Hayagriva, Who is whitish and is seen with 'jnana mudra', a book, 'japa mala', and a white conchshell respectively in each of His hands. He is the presiding Deity of knowledge and was brought there by Vadiraja Tirtha, the twentieth swami of the Sode Mutt who appeared around the sixteenth century and lived for 120 years.

In the Madhwa Vijay (15:96-116.) there is a nice description of the final pastime of Visnu Tirtha joining Madhwa after the passing away of their parents at Pajaka-ksetra which will be included later.

Srila Trivikrama Panditacarya.
Sriman Trivikrama Panditacarya took his birth in the family of Likuca (Pejjataya) like Madhwa, near modern day Kasagar. He was a 'Shivalli Brahmin', and His father was Subrahmanya Pandit of the 'Angirasa Gotra'. Trivikrama was the eldest of three sons, and he emerged as a scholar of the Monist Adwaita school, although he never saw himself as a 'mayavadi', because he was never satisfied with it's conclusions.
 He became the court pandit of Jayasimha Maharaja, the King of Kumbla. There is an incredible story of the meeting between Trivikrama, the King and Madhwa, during which Madhwa stated all known philosophies, and one by one smashed them all. He then lured the court pandit into a debate and over fifteen days changed the mind of the doubting Trivikrama into a Madhwa Vaisnava. After being soundly defeated by Madhwa at Visnumangala and becoming Madhwa's disciple, Trivikrama wrote three books. Madhwacarya showed him many favours, due to his devotion and dedication. Trivikram Panditacarya was a householder. His youngest son was Narayana Panditacarya who is the compiler of the biography of Madhwa (Madhwa Vijay) from which I have taken the details surrounding Madhwa's life for the compilation of this book. He too was very learned, and devoted to Madhwa. There are about twenty books accredited to Narayana Panditacarya. He spent about thirty years growing up in the association of Sripad Madhwacarya.
