It is impossible to describe the experience accurately. I felt the point of consciousness that was myself growing wider, surrounded by waves of light. It grew wider and wider, spreading outward while the body, normally the immediate object of its perception, appeared to have receded into the distance until I became entirely unconscious of it.
I was no longer myself, or to be more accurate, no longer as I knew myself to be, a small point of awareness confined in a body, but instead was a vast circle of consciousness in which the body was but a point, bathed in light and in a state of exaltation and happiness impossible to describe.
After some time, the duration of which I could not judge, the circle began to narrow down. I became suddenly aware of the noises in the street, felt again my arms and legs and head, and once more became my narrow self in touch with body and surroundings.
