Pandit Bhavani Sankar

Shot in the dark-

A lesser known- figurein the early Theosophical Movement, Hindu Brahmin, Pandit Bhavani Shankar has seemed to remain generally unnoticed.  His only text written parallels T. Subba Rao's four lectures on the Bhagavadgita.  His text is simply called "The Doctrine of the Bhagavadgita."

I have recently stumbled upon a Hindi text; "Dharma-Karma-Rahasya," written by a Pndt. Bhavani Shankar, to which I believe might be the same person, yet I have no way of finding out, as the book seems to be just as obscure as the person who has written it.
