It happens exactly like that. There are seven chakras but they don’t exist in the same Places for all people. And there are experiences but they never happen in the same way to two persons — they happen very, very differently. So there is no need to know the physiology of the kundalini, and there is no need to know the chakras, and there is no need to know what happens finally — because if you know it you will start hypnotizing yourself, and by and by you will start getting into the ritual. And you will create a kind of dream around you. And when there are many people doing the same thing, you tend to fall into the crowd-mind. You start swaying with the crowd.
