“The difficulty in realizing this to be so is that conceptual thinking
cannot grasp it. It is as if the eyes were trying to look at themselves
directly, or as if one were trying to describe the color of a mirror
in terms of colors reflected in the mirror. Just as sight is something
more than all things seen, the foundation or ‘ground’ of our existence
and awareness cannot be understood in terms of things that are known.”
Alan Watts, the Book p.16 (1957)
