1. Years ago when I was an LSD dabbler I had the experience, lying on my back on a mesa, that all moments were one moment and that time was a continuum with no beginning or end. I thought, This must be what holy men know. Then I heard a swooshing, aerodynamic sound, and I saw that a vulture had homed in on me, and I stood up and waved my arms and shouted, “I’m not dead.” Even now, though, I wonder, are all moments somehow one moment, or had a change in the chemistry in my brain simply persuaded me that they were? Had I briefly visited an exalted and actual state of being, one adjacent to ordinary awareness, or did I imagine that I had? Had I perhaps had an intimation of the non-spatiotemporal realm? I find I can’t answer the question. I raise it only to point out that in some circumstances what is the inner world and what is the outer world and how they are joined is not completely clear.
