And here is a good description of two "levels" or maybe, better, "sorts" of experience, from Gerald May:
"On a winter evening I rest my back on the tree's great trunk and watch the sun set far across a mounded white snow meadow, ruby roundness settling steadily, behind darkening tree-bones in the distance, pink splashes through the western sky. For a long moment I am inside this particular sunset, rolling in it like a child in new hay. I am simply experiencing: I must be the experience, for it is all there is. Then self-awareness comes, recognizing the beauty and the bliss, wanting to prolong it, somehow to hold it forever, and I know that I am here, having this experience. The self-consciousness makes me feel just a little separate from the sky and the soft bark of the tree on my back and the sun now gone beyond the horizon. Now I am an observer, an experiencer, and this sunset has become something I am perceiving, an experience I'm having."
