We can tune up our awareness, dredge up each separate piece and bring it out into the light. We can make the unconscious conscious, slowly, one piece at a time. The essence of our experience is change. Change is incessant. Moment by moment life flows by and it is never the same.
Perpetual alteration is the essence of the perceptual universe.
A thought springs up in your head and half a second later, it is gone. In comes another one, and that is gone too. A sound strikes your ears and then silence. People come into your life and they leave again. Friends go, relatives die.
