I describe the variety of different kinds of experiences I had, from seeing into the future to being inside the body of a bird and feeling the bird consciousness, to being in a plane of existence with beings that do not exist on this planet at all. And I described my experiences to shamans who started to laugh, saying, "Oh, we know those guys."

I believe, or sense, that the universe has not been constructed from a purely mechanical, logical, rational point of view, but there is a magic afoot in the universe, that God can be looked at as a kind of a magician in which we get to perform tricks ourselves, without knowing that we're doing so.

We all get out, maybe for longer than we wish, because we all pass this mortal coil more or less and so we certainly get a chance to experience it again, and we've experienced it before we were born. So it's more or less our natural place of being, unless you believe that the only time you're conscious is when you're alive.

A lot of things occurred to me with shamans in Peru.There were a number of different kinds of experiences that you learn from doing ritual and taking ayahuasca [a common tropical forest hallucinogen] is the key to understanding the native consciousness and perception of the world with the Peruvian shamans that you wouldn't get unless you had been with them, but every shamanic tradition, including the Native American tradition of medicine and cleansing ritual, like the Sun Dance or the sweat lodge.

What I thought was unreal now, for me, seems in some ways to be more real than what I think to be real, which seems now to be unreal

When I speak or when I offer ideas and explain how the universe seems to work from the point of view that I've understood, it seems to give people a lift - an unshackling or freeing.

You had to be able to lift yourself outside of the time stream - and that essentially became what is called the yoga of time travel.
