I want to explain the new alchemy [in the "From Earth, Air, Fire, and Water to a New Vision of Mind and Time"], which has to do with understanding what I call the subjective and objective qualities of existence.

The kinds of mystical experiences that I have had definitely convinced me that I was able to get out of time. I have had experiences, or brief glimpses, of being able to see the future and then come back into time, and then go into extraordinary realms of the past.

Alchemy and Kabbalah are later developments in my thinking. I think the primary interest has been the relationship of magic and mystery to logic and understanding. Those are the primary driving forces of my life. I have this ability, for some reason, to be able to hold both the Magical MysteryTour we're on in conjunction with the logical rigor of understanding theoretical physics, which makes me kind of a rare bird, because usually you're one or the other.

We have a sense of continuity, which gives us what we call a sense of time. Through our ability to have remembrances of both what's coming and what's happening and what has happened, we begin to piece together a logical picture of the world.

I am not talking to you from the point of view of just wishful thinking, or imaginary craziness. I'm talking to you from a deeper basic understanding - quantum physics really begins to point to this discovery, it says that you can't have a universe without mind entering into it, the mind is actually shaping the very thing that is being perceived.

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.

The old alchemy, or what was just called alchemy, has a history. Most people, if they've been trained in sciences, think of alchemy as the precursor to chemistry. Back in time, people were called alchemists and they worked for kings and rich people, smelting metal and trying to change base metal into gold, because the king wanted to be richer.
