Osho, The Vigyana Bhairava Tantra vol. one, #38:
BATHE IN THE CENTER OF SOUND, AS IN THE CONTINUOUS SOUND OF A WATERFALL
This technique can be done in many ways. One way is to begin by just sitting anywhere. Sounds are always present. It may be in a market or it may be at a Himalayan retreat: sounds are there. Sit silently, and with sound there is something very special. Whenever there are sounds, you are the center. All the sounds come to you from everywhere, from all directions.
With sight, with eyes, this is not so. Sight is linear. I see you — then there is a line toward you. Sound is circular, it is not linear. So all sounds come in circles and you are the center. Wherever you are, you are always the center of sound. For sounds, you are always God, the center of the whole universe. Every sound is coming to you, moving toward you, in circles.
This technique says, BATHE IN THE CENTER OF SOUND. Wherever you are, if you are doing this technique, just close your eyes and feel the whole universe filled with sound. Feel as if every sound is moving toward you and you are the center. Even this feeling that you are the center will give you a very deep peace. The whole universe becomes the circumference and you are the center, and everything is moving toward you, falling toward you.
… AS IN THE CONTINUOUS SOUND OF A WATERFALL.
If you are sitting by the side of a waterfall, close your eyes and feel the sound all around you, falling on you from every side, creating a center in you from every side. Why this emphasis on feeling that you are in the center? Because in the center there is no sound. The center is without sound, that is why you can hear sounds; otherwise you could not hear them. A sound cannot hear another sound. Because you are soundless at your center, you can hear sounds. The center is absolute silence. That is why you can hear sounds entering you, coming to you, penetrating you, encircling you.
If you can find out where is the center, where is the field in you to where every sound is coming, suddenly sounds will disappear and you will enter into soundlessness. If you can feel a center where every sound is being heard, there is a sudden transference of consciousness. One moment you will be hearing the whole world filled with sounds, and another moment your awareness will suddenly turn in and you will hear the soundlessness, the center of life.
Once you have heard that, then no sound can disturb you. It comes to you, but it never reaches you. It is always coming to you, but it never reaches you. There is a point where no sound enters. That point is YOU. Do it in a market, there is no other place like a market. It is so much filled with sounds, mad sounds. But do not start thinking about sounds — that this is good and that is bad, and this is disturbing and that is very beautiful and harmonious. You are not supposed to think about sounds, you are simply supposed to think of the center. You are not supposed to think about every sound moving toward you — whether it is good, bad, beautiful. You are just to remember that you are the center and all the sounds are moving toward you — every sound, whatsoever the sort.
