"There's another kind of a stupid thing, or a bhootish thing maybe, that people ask you to meditate here (at Agnya), it’s absolutely wrong. [Even though] in Gita it is written, still it is wrong. Nobody should put attention here. If they have to put attention, put attention at the door. What's the use of looking at a window? You can't get out of it, can you? If you have to look at anything, be on the lookout for the door. And the door is here. The door of Sahasrara is to be opened out, so you should not try to concentrate on this part.
Many people who have concentrated on this part have become mad. When they become mad, people say "He's a Yogi, but has got unmanitasha” - that he moves like a madcap. How can a yogi be a madcap? That means he's united with God, is He mad? All such mad people are really mad! They have nothing to do with God, definitely!
But, there are people who believe in such things - "Oh, he is in love with God, so he just jumps on the stage and goes into ecstasy, dances like a madcap." How can God be mad? First position is this, that the sanest personality is God. Has to be. From where do the sanity comes in?
So, this is one thing one has to understand, that any such practices can lead you to lunacy, and one should do it."
