Anahad Nad

Deep within you there is a music which is not created by anybody, which is not created by hands, which is not produced on any instrument. There is a special name for it; it is called Anahad. When you play on a guitar it is called Ahad, because you strike on the strings with your fingers. Ahad means striking. It is created out of conflict, there is a little aggression in it, there is struggle. The musician is struggling to create music on the instrument, there is a kind of fight.
But in the innermost recess of your being there is neither instrument nor musician, but music is there, without the musician and without the instrument. Zen people call it "The Sound of One Hand Clapping". The Christian mystics call it "The Soundless Sound". It is a silence and yet it is musical silence.

These words of T.S. Eliot will be significant:

The still point... There is a point within you where nothing ever moves - no movement from or to, no stirring, no sound created by any instrument. Nobody is there, just stillness, but that stillness is the dance and that stillness is the music. It is called Anahad.

Kabir says, "I am hearing some strange music, as if bells are ringing, but nobody is shaking them."

The sound of one hand clapping, Anahad Nad, unstruck music... All other music is struck music; you have to strike the strings of the instrument. It is only by striking the strings that the music arises. It is violence - playing on a guitar or on a sitar, you are being a little violent. It is a kind of coercion; you are forcing the instrument to release the music. It is a kind of fight. And there is duality: the musician and the musical instrument in conflict, fighting. It can′t be great music, it can′t be eternal music. Once the musician stops fighting the music will disappear. It is caused, so it cannot be eternal.
But when you turn in, there is light and there is music - music which is eternal. It is simply there, it is not a created phenomenon.
