"Tradition established, under directions of the holy Babaji, is that Kriya has to be obtained directly from a Kriya Yoga Guru and to be handed down from the Guru to the initiate in a continuous chain. A Kriya Yogi can only act as a Kriya-Guru when allowed to do so under permission from his own Guru.
Disciples of Lahiri Mahasaya used to be told to keep the teachings a closed secret and not to talk about it even with friends and relations who were not initiated into the secrets. So religiously this direction was followed that in cases even Kriya performers living as neighbours over twenty years did not know each other as members of the same spiritual fraternity."
- Sri Sailendra Bejoy Dasgupta, Chapter 5, Kriya Yoga
