the definition

"He thought he saw the Great Dance ... and that part of him which could reason and remember was dropped farther and farther behind that part of him which saw. Even then, at the very zenith of complexity, complexity was eaten up and faded, as a thin white cloud fades into the hard blue burning of the sky, and a simplicity beyond all comprehension, ancient and young as spring, illimitable, pellucid, drew him with cords of infinite desire into its own stillness. He went up into such a quietness, a privacy, and a freshness that at the very moment when he stood farthest from our ordinary mode of being he had the sense of stripping off emcumbrances and awaking from a trance, and coming to himself..."
C.S. Lewis - _Perelandra_
