Prabhupāda: Jīva Gosvāmī has got six sandarbhas, theses: Bhagavat-sandarbha, Kṛṣṇa-sandarbha, Tattva-sandarbha, Prīti-sandarbha, like that. So these books are...

Our, this Gauḍīya-sampradāya... We belong to Gauḍīya-sampradāya—Lord Caitanya Mahāprabhu, from the disciplic succession of Caitanya Mahāprabhu. We have got immense literature to understand God. One who wants to understand God through philosophy, science, argument, logic, so to supply them material, we have got immense literature, Vedic literature. So one of them is mentioned here, Kṛṣṇa-sandarbha, what is Kṛṣṇa. Go on.
