Krsna-Sandarbha is the fourth work in the series of Sandarbhas. Tattva Sandarbha deals with the nature of proof. The Bhagavat and Paramatma
Sandarbhas deal with the natures of the Lord as Bhagavan and Paramatma, and as well the nature of jiva and prakrti. A separate sandarbha is not dedicated to Brahman, since it has no qualities and thus its description is brief. Krsna Sandarbha deals with the nature of Krsna, who is a form of Bhagavan,but special because
He is the complete manifestation of all of Bhagavan’s qualities.
