I recently acquired a copy of a Sanskrit commentary on the Sarva-samvādinī, which is a commentary by Śrī Jīva Goswami on his Sandarbhas. It is written by Śrī Ānanda Gopāla Vedānta-tirtha, who is a Gauḍiya-Vedānta scholar currently based in Rādhā-kund. The book was published by the Jīva Institute in 2017.
That a Sanskrit scholar in modern times has written a Sanskrit commentary on the Sarva-samvādinī is fascinating to me. I also rather like reading his Sanskrit as it is quite easy to follow and contains much valuable information. For example, I came across this rather interesting chart that traces Śrī Jīva’s lineage.
There is still some genuine scholarship left in Gauḍiya Vaiṣṇavism!
