Osho explains a meditation from the Vigyan Bhairav Tantra.
Bathe in the center of sound as in the continuous sound of a waterfall.
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. 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.
The center is without sound, that is why you can hear sounds – a sound cannot hear another sound. 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.
Do not start thinking about the sounds – that this is good and that is bad, and this is disturbing and that is very beautiful and harmonious. Simply think of the center. Just remember that you are the center and all the sounds are moving toward you – every sound, whatsoever the sort.
Sounds are not heard in the ears, the ears cannot hear them. The ears only do a transmission work, and in the transmission they cut out much which is useless for you. They choose, they select, and then those sounds enter you. Now find out within, where is your center. The ears are not the center, you are hearing from somewhere deep down. The ears are simply sending you the selected sounds. Where are you? Where is your center?
