PAULINE OLIVEROS November 1971
from Sonic Meditations
Find your place in a darkened indoor space or a deserted out-of-doors area. Mentally form a sound image. Assume that the magnitude of your concentration on, or the vividness of this sound image will cause one or more of the group to receive this sound image by telepathic transmission. Visualize the person to whom you are sending. Rest after your attempted telepathic transmission by becoming mentally blank. When or if a sound image different from your own forms in your mind, assume that you are receiving from some one else, then make that sound image audible. Rest again by becoming mentally blank or return to your own mental sound image. Continue as long as possible or until all others are quiet.
