I'm writing this cos my (sort of-) siksha guru Sri Raman Bihari Das Babaji occasionally sings songs from this sampraday that he learnt when he was living at Radha Kant Mandir with his Gurudev Sri Vinod Vihari Goswami in the early 80s.
one of the songs goes:
jay radha vallabha, sri hari bangsh
jai sri vrindavana sri vanachandra
which includes the names of Gurus in that line.
Does anyone know anything else about them, how they differ from Chaitanya-ite vaishnavas in mood and emphasis. I did read something about them in the very lovely Journey through the 12 forests by Haberman(?) but would like to know if anyone else has anything else to add
cheers
Ananga
