As a long-time dabbler in physics and mysticism myself, it seems the more I dabble the more I become convinced that a major common denominator among mystics of all flavors is that they have experienced a revelatory insight into the true nature of TIME, as discrete moments each of which is a complete and freshly created universe unto itself.

Surprisingly, some physicists such as David Deutsch in 'The Fabric of Reality' will describe essentially the same thing, even without having evidently any subjective experience of it whatsoever (e.g. "Time does not flow. Each moment is an instance of another Universe.") Some acquaintance with physics and physicists has impressed upon me how little is really known about Time per se, as opposed to, for example, Gravity. (e.g. physicist Paul Davies' book 'About Time')

It is interesting, and even, ahem, enlightening (hehe), to me to listen to Zen master Dogen's essay 'Being-Time' after reading Eckhart Tolle. For example at the mp3.com artist site 'freedharma', there is a copy of Dogen's 'Being-Time' essay. Or check out Gary Snyder's audio recording of Kaz Tanahashi's Dogen translation 'Moon in a Dewdrop'.
