Meditation implies a mind that is so astonishingly clear that every form of self-deception comes to an end. One can deceive oneself infinitely; and generally meditation, so-called, is a form of self-hypnosis—the seeing of visions according to your conditioning. It is so simple: if you are a Christian you will see Christ; if you are a Hindu you will see your Krishna, or whichever of the innumerable gods you have. But meditation is none of these things. It is the absolute stillness of the mind, the absolute quietness of the brain.
The foundation for meditation has to be laid in daily life, in how one behaves, in what one thinks. One cannot be violent and meditate; that has no meaning. If there is, psychologically, any kind of fear, then obviously meditation is an escape. For the stillness of the mind, its complete quiet, an extraordinary discipline is required; not the discipline of suppression, conformity, or the following of some authority, but that discipline or learning which takes place throughout the day, about every movement of thought. The mind then has a religious quality of unity. From that there can be action which is not contradictory.
