It was quite something. I am reluctant to describe it as life-changing, as out of body experiences real and imagined tend to lend themselves to hyperbole, wishful thinking and exaggerated memories, especially in the near term. Best to wait till the luster wears off. In any case I can tell you it was an amazing journey, from beginning to end, each experiential component building on the realizations and self-knowledge gained from preceding components, until the lines between episodes blurred and became one (yeah, very Buddhist). Up there it is huge, just huge, and you couldn't help but see the absolute insignificance of your self and your overblown self-perception. Unlike down here where we've built vast systems of interference between who we are and the real, up there there's nothing to block it out. It's right there in front of you all the time you're passing through it, and, at least in my case, it became fully manifest that the world I perceive is not the world that is, and neither am I the person I take myself to be.
