I don't agree with the Ritviks. Srila Prabhupada was very clear that He is not God. But I also don't agree with the ISKCON management and "approval" system of guru "selection."
This is all simply control by mechanical means on the material platform.
So what about initiation? Initiation is by hearing from the pure
devotee. Associate with those who are initiated in this way. The future
of the Hare Krishna movement will be secure. Srila Prabhupada's mission will be successful.
