Every book I write is filled with ideas to open people's minds. And many of my books are intended for the lay mind, for people who have no idea about what's going on in quantum physics. They are meant to get big ideas across in the simplest way so young people can start to wrestle with these ideas.

Certainly in terms of technology, it's made a tremendous impact, but medicine is still within the realm of what we might call "objective" science. It's still part of the objective way of looking at the world.

In the Greek way of dealing with alchemy, which was earth, air, fire and water, these were the objective qualities. Within the objective qualities - things of earth, air, fire and water - are our subjective experiences of hot, cold, dry, and moist.

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.

Medicine could have pretty far-reaching effects once we begin to look at the kinds of things that people can do to induce transformation in their thinking, their sensing, their intuiting and their feelings - and whether there's some power there that can be unleashed that would cause blockages that were primarily put in place through thought to be let go of.

The most common way people could do time-travel would be a form of meditation in which you don't get caught up in your thoughts and don't make patterns of logical consequences follow as a result of your thinking process. It's very hard for most of us to do that if we think about it. But if you start to watch the process by which things come into being, and you begin to witness from the point of view of watching the words form, then you're beginning to move into the non-temporal mindset, or that which is free of time.

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.
