mrbigfoot replied to sreeram's topic in Mantra Tantra VigyanaThere is a book which lists what u are asking about - Ullu Tantra, Dehati Pustak Bhandar, nd. Skt and Hindi. Collection of material relating to Ullu (Owl), an aspect of Kali. If u have come across anything useful please let me know. It is really disheartening to know that after the tiger the owl is the most endangered species in india because of its poaching for these purposes.
