Let’s say you have the experience of tranquility. Whatever the cause of it. You’re feeling tranquil inside. Then your body makes Valium, —just like the one that Haufman Laroche makes, only it doesn’t make you feel like a zombie—. This is the real material equivalent of tranquility.
When you feel anxious, your body makes jittery molecules. They’re not just made from the adrenal glands. They’re made everywhere in the body. Each cell of the body is making jittery molecules: adrenaline, noradrenaline, cortisol, etc. Now it turns out that when you feel exhilarated, whatever the reason for the exhilaration, your body makes very powerful immuno-modulators. They’re in fact, anti-cancer drugs known as interleukins and interferons. Recently, interleukins were used, for example, in the treatment of cancer. They’re very expensive. A full course of interleukin 2 might cost you something like $40 000 for a full treatment. But if you go on Magic Mountain in Disney World, you can make millions of dollars worth of interleukin 2. That is, of course, given the fact that that’s your idea of fun. If your idea of fun is that magic ride, you’ll make interleukin 2. On the other hand, if you interpret that as not a good experience, then your body will make harmful chemicals. In other words, the interpretations of reality that we make to ourselves are generating from inside us all kinds of drugs. We have a pharmacy here that is absolutely exquisite. It makes everything. It makes tranquilizers, sleeping pills, anticancer drugs, immuno-modulators, antibiotics, you name it, the body can make it, in the right dose, at the precise time, for the right target organ, no side effects, and all the instructions are contained in the packaging.
