In this way some say that Vijayadhiraja Tirtha called Kavindra due to
a need for the preaching to spread due to his talents in that direction,
but one cannot guess the reasons why - a pure Vaisnava acts. We do know,
that it is only to satisfy the Lord, that much we can ascertain. The line
coming from Rajendra Tirtha is now represented by Sripad Vyasa Tirtha (Vyasaraya
Mutt) and Sosale Mutt, and those lines still continue.
The other, or second line (that from Kavindra Tirtha) continued on to Vagisa Tirtha and Ramacandra Tirtha, but at the time of Ramacandra there was some heavy disagreements at the time of his passing that apparently nearly stopped the line at that time. This is the second bifurcation that B.N.K. Sharma refers to which inevitably it caused a big spilt and now those lines come down via his two disciples, Vibudhendra Tirtha of Raghavendra Swami Mutt and Vidyanidhi Tirtha of Uttaradi Mutt.
It is said that Vibudhendra Tirtha (1400-1470.) who took the pontiffical seat in the Raghavendra Swami Mutt between (1435-1470.), was also a disciple of Sripad Rajendra Tirtha, and the great Sripadaraj Tirtha was Vibudhendra Tirtha's student(B.N.K. Sharma.1961. History of the Dvaita School of Vedanta. page 210.).
It is suggested that Sripad Rajendra Tirtha in fact had many disciples
in North India where he preached, such as Visnudasacarya. This Visnudasacarya
it appears made quite an impression in North India with his great dialectical
works, Vadaratnavali, Khandana-Khandana and Vivarana Vidambana, nearly
a hundred years before Vyasa Tirtha(B.N.K. Sharma. History of the Dvaita
School of Vedanta. page 540.); and the redoubtable Vibhudendra Tirtha is
believed to have gained fresh following to Madhwa 'siddhanta' in upper
Karnataka and elsewhere by his dialectical power and active propaganda(B.N.K.
Sharma. 1961. History of the Dvaita School of Vedanta. page 540.).
It is important to point out that this Visnudasacarya (1390-1440.) is different from Visnu Puri who was the disciple of Rajendra Tirtha's disciple Jayadharma Tirtha (Vijayadhwaj Tirtha), and who received glorification for compiling a commentary on Srimad Bhagavatam that in his olde age he presented to Lord Chaitanya Mahaprabhu called Bhakti Ratnavali.
Sripad Vidyadhiraja Tirtha passed away at Ergola near Malked. The old
town of Ergola now lies in ruins and this is believed to be where the 'samadhi'
tombs of both Sriyuts Vidyadhiraja and Rajendra Tirtha are.
"However during my visit to the place which is some four miles from Nalvar (on the Wadi-Raichur section) on 28th February 1975., I found that the old town of Ergola was situated within the old fort now in ruins. The tombs of Vidyadhiraja (Rajendra and some others) may have been in the old town now in ruins."(B.N.K. Sharma. 1961. History of the Dvaita School of Vedanta. page 452.)
