“[C]hange is not merely a force of destruction. Every form is really a pattern of movement, and every living thing is like the river, which, if it did not flow out, would never have been able to flow in. Life and death are not two opposed forces; they are simply two ways of looking at the same force, for the movement of change is as much the builder as the destroyer. The human body lives because it is a complex of motions, of circulation, respiration, and digestion. To resist change, to try to cling to life, is therefore like holding your breath: if you persist you kill yourself.

In thinking of ourselves as divided into “I” and “me,” we easily forget that consciousness also lives because it is moving. It is as much a part and product of the stream of change as the body and the whole natural world. If you look at it carefully, you will see that consciousness— the thing you call “I”— is really a stream of experiences, of sensations, thoughts, and feelings in constant motion. But because these experiences include memories, we have the impression that “I” is something solid and still, like a tablet upon which life is writing a record.

Yet the “tablet” moves with the writing finger as the river flows along with the ripples, so that memory is like a record written on water— a record, not of graven characters, but of waves stirred into motion by other waves which are called sensations and facts.”
