“Appreciating the mind as `ALL SILENCE'. `I AM' is meditation.”

The meditator is the observer, the senser, the thinker, the experiencer, and when there is the experiencer, the thinker, then he is concerned with reaching out, gaining, achieving, experiencing. And that thing which is timeless cannot be experienced. There is no experience at all. There is only that which is not nameable. ...You know, in all this there are various powers like clairvoyance, reading somebody’s thought — which is the most disgusting thing to do: it is like reading letters that are private. There are various powers. You know what I am talking about, don’t you? You call them siddhis, don’t you? Do you know that all these things are like candles in the sun? When there is no sun there is darkness, and then the candle and the light of the candle become very important. But when there is the sun, the light, the beauty, the clarity, then all these powers, these siddhis — developing various centres, chakras, kundalini, you know all that business — are like candlelight; they have no value at all. And when you have that light, you don’t want anything else.

"What is Meditation?" (2006)
Context: Mind without agitation is meditation. Mind in the present moment is meditation. Mind that has no hesitation, no anticipation is meditation. Mind that has come back home, to the source, is meditation. Mind that becomes ‘‘no mind’’ is meditation.

They are repetitive, producing mechanical activities which are a necessary part of existence. But they are only part, and thought and feeling cannot possibly enter into the immensity of life. Quite a different approach is necessary, not the path of habit, association and the known; there must be freedom from these. Meditation is the emptying of the mind of the known. It cannot be done by thought or by the hidden prompting of thought, nor by desire in the form of prayer, nor through the self-effacing hypnotism of words, images, hopes, and vanities. All these have to come to an end, easily, without effort and choice, in the flame of awareness.
