Sanatana Gosvami wanted to confirm the fact that Sri Caitanya Mahaprabhu is the incarnation of Krsna for this age. According to sastra, in Kali-yuga the Lord would assume a golden or yellow color and would distribute love of Krsna and the sankirtana movement. In accordance with sastra and saintly persons, these characteristics were vividly displayed by Sri Caitanya Mahaprabhu, and it was therefore clear that Sri Caitanya Mahaprabhu was an incarnation of Krsna. He was confirmed by the sastras, and His characteristics were accepted by saintly people. Since Sri Caitanya Mahaprabhu could not escape Sanatana Gosvami's argument, He remained silent on this point and thereby indirectly accepted Sanatana's statement. By this we can clearly understand that Sri Caitanya Mahaprabhu was the direct incarnation of Lord Krsna.
