taatparya (summary):

the young vaasudeva was so intent in the path of seeking parabrahman that he decided the only way to stay focussed is to become a sanyaasi.  He obtained sanyaasa from shree achyuta prekShacharya,  Having obtained the sanyaasa, and to stay true to the prescribed duties of the sanyaasa ashrama, he was engaged in disseminating the correct knowledge of vedic philosophy through discourses and debates as well as teach all his disciples (including his shree achyuta prekSha who gave him the sanyaasa ashrama).  While doing this, he did not omit observance of the traditional rituals and practices.  All this is described in detail in the fourth canto of the shree madhva vijaya.
