Meditation is not concentration. Meditation demands an astonishingly alert mind; it is the understanding of the totality of life in which every form of fragmentation has ceased. Meditation is to be aware of every thought and of every feeling, never to say it is right or wrong, but just to watch it and move with it. In that watching you begin to understand the whole movement of thought and feeling.
And out of this awareness comes silence. Silence put together by thought is stagnation, is dead, but the silence that comes when thought has understood its own beginning, the nature of itself, understood how all thought is never free but always old — this silence is meditation.
Meditation is a state of mind which looks at everything with complete attention, totally, not just parts of it. And no one can teach you how to be attentive. When you learn about yourself, watch yourself, watch the way you walk, how you eat, what you say, the gossip, the hate, the jealousy — if you are aware of all that in yourself, without any choice, that is part of meditation.
