the friends should do their best to make as many converts among the Hindus as they possibly can.

The origins of this and many other religions that abound in India are not quite known to us, and even the Orientalists and the students of religion 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 wellnigh bewildering, with the view of bringing the Message to the Hindus. The task of converting this section of the Indian population is a most vital obligation, although the Guardian is fully aware of the many difficulties that it presents. Nevertheless the friends should do their best to make as many converts among the Hindus as they possibly can.
