soundless flow

And then there is the question of time. What for instance is an instant? Hours, minutes, seconds, even, these are comprehensible, since they can be measured on a clock, but what is meant when people speak of a moment, a while—a tick—a jiffy? They are only words, of course, yet they hang above soundless depths. Does time flow or is it a succession of stillnesses—instants—moving so swiftly they seem to us to join in an unbreaking wave? Or is there only one great stillness, stretching everywhere, in all directions, through which we move like swimmers breasting an infinite, listless sea? […] There are lights now in the sky that set out from their sources a billion years ago. But are there lights? No, only light, flowing endlessly, moving, every instant.
Everything blurs around its edges, everything seeps into everything else. Nothing is separate.
