Reality includes both the past and the future, but existence includes only the present and is totally dependent on the reality of past and future universes. Without them there is no existence now.

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.

Chemistry comes about through the transformation of earth, air, fire and water. All chemistry is just movement within those things, and so we experience the joys and the sorrows of hot and cold, and dry and moist, because of these chemical transformations. In a similar way, we create and experience a world of time, space, motion and energy, through our intuitions, our thoughts, our sensing and our feeling.

People who are creative often will spend hours doing something and come out of their period of creation and not even notice that hours have passed. In that sense, they're able to time travel.

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 quantum is that embarrassing little piece of thread that always hangs from the sweater of space-time. Pull it and the whole thing unravels.
