Molecules form and dissolve, returning to the primordial soup of atoms. But consciousness survives the death of the molecules on which it rides. What was once a bundle of energy in a sunbeam turns into a leaf, only to fall and change again into soil. The change of state crosses many boundaries. A sunbeam is invisible, whereas leaves and soil are visible.A leaf is alive and growing,whereas sunbeams aren't.the colors of light, leaf, and soil are different, and so on. But all these transformations exist as constructs of the mind.The actual energy present in the sunbeam experiences no change at all.
