Sarva-samvadini is a supplement to the Ṣaṭ Sandarbha of Śrī Jīva Gosvāmī. In this book, Śrī Jīva Gosvāmī adds extra information on certain topics discussed in the Sandarbhas. It is in this book that he names the philosophy and theology of Śrī Caitanya Vaiṣṇavism as Acintya-bheda-abheda. The language of the book, however, is highly philosophical. Paṇḍita Ānanda Gopāla Dāsa of Jīva Institute has written a lucid commentary on it in Sanskrit. This is the maiden commentary on this important work. It is a must for those who really want to dive deep into the siddhānta of Caitanya school.
We can’t know our father because we did not exist at the time of conception. We can’t know our mother because we have no awareness at the time of birth. Yet we accept them with full faith. Similarly, we can’t know God, but we should accept on the authority of sastra, and holy people.
