"If you want to move something, you've got to move it with your mind"

If there's one thing that Zen Masters, people who have survived the concentration camps and people in This Thing of Ours all understand, it is that the body is actually an extension of the Mind (in the fuller, "soul" sense of mind, then the mere chatterbox in your head). If you get sick from being out in the rain, it is because the rain made your mind sick before it could make your body sick.
Of course, the mathematical relations between "objects" exist. F=ma and all that, but the objects themselves are created by our definition of them. So there is a strange relationship in the universe between "subjective" and "objective" reality.
