Meditation is a state. You are simply silent -- no thought to concentrate on, no subject to contemplate, no object to meditate over. The other has disappeared. And remember, the moment the other disappears, you cannot exist. You are part of the other. Just as if light disappears, there will be no darkness; if life disappears, there will be no death; they are intrinsically joined together. "I" and "you" can either exist together in a certain kind of coexistence or we have to disappear and then what remains is neither me nor you. What remains is the universal energy.

Meditation is disappearing into the universal.

Mind is the barrier. And the more you concentrate, the more you contemplate, the more you meditate upon something, you will never go out of the mind. And mind is the dewdrop I have referred to. So the first thing to understand is that for meditation, only in the East and particularly in India was the first word coined. Words are coined only when you have a certain experience which is incapable of being expressed in the existing language.
