Even though the Indian Hindus are very much inclined in my favor, so far I have experience it is very difficult to turn them into pure devotees. The difficulty has become more acute on account of Ramakrishna Mission's preaching that any opinion about religion is alright. But our philosophy is different, we do not accept any opinion which is not advised by Krishna. So unless one is very fortunate, never mind whether he is Hindu or non-Hindu, one cannot take to the Krishna Consciousness movement and accept its bona fide principles.
