In the course of the daily flow of unmoderated experience and the full spectrum of human emotions, in the midst of feeling mildly excited, or sluggish, or hungry, or looking forward to dinner, you might find yourself struck for the smallest indivisible moment by the sudden sensation of just how eternally strange and wondrous it is that there is something here rather than nothing, or by monumentally deep gratitude that there is a box of tissues at hand when you need to blow your nose. When this happens, take note of that sensation as deeply as you can, and be sure to note its every minute expression in the mind and body.
