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.
It is very difficult to understand that my happiness does not depend on anyone else. Our whole childhood training is that my happiness depends on others. My happiness actually depends on my own state of mind, which has nothing to do with what others say or do.
