In Sankaradeva and Madhavadeva’s works, there are two components: one is the teaching and the other is the call to action. The latter is represented invariably in their works by a section called upadesa while the teaching is a broader aspect; it is the philosophical basis of the faith and of the system and indeed of the entire outlook on life that is suggested by the doctrine of eka sarana. This teaching seems to primarily revolve around the discrimination of the tattvas, the tattva viveka, via a description of the creation of the macro and microcosms by the supreme pure-personality and their evolution by His benign preserving influence. Of course, a puranic narrative is adopted in which these tattvas—the jada tattvas, as distinguished from the Lord—are dressed up in anthropomorphic garb and given the forms of personalities. This makes up a tale—a katha—in which the supreme pure-person is shown to direct, interact with, and, in the case of Krsna, even play with these personified forms; and His superiority to these forms is shown and further, the jivas are revealed not to be of the nature of these personalities—not the parts of matter—in actuality, but the parts, the amsas, as it were, of the Lord Himself.
