Baha'i central figures knew nothing about Hindu religion!
"...The origins of this (Hinduism) and many other religions that abound in India are not quite known to us, and even the Orientalists and the students of religions are not in complete accord about the results of their investigations in that field. The Bahá'í writings also do not refer specifically to any of these forms of religion current in India. So, the Guardian feels it impossible to give you any definite and detailed information on that subject. He would urge you, however, to carry on your studies in that field, although its immensity is well-nigh bewildering, with the view of bringing the Message to the Hindus...."
