About the Author
"Jiva Gosvami has got six Sandarbhas, theses: Bhagavat-sandarbha, Krsna-sandarbha, Tattava-sandarbha, Priti-sandarbha, like that. So, I don't think that these books are published in English. These Sandarbhas of Jiva Gosvami are so philosophically discussed that throughout the whole world, there is not a single philosopher who can defy them. We belong to the Gaudiya-sampradaya from Lord Caitanya Mahaprabhu, coming in the disciplic succession of Caitanya Mahaprabhu. We have got immense literature to understand God. One who wants to understand God through philosophy, science, argument and logic, to supply them reading material, we have got immense literature, Vedic literature".
