Philip K. Dick and the alchemists

letter to Claudia Bush (Exegesis p. 176)

what happened to me in March is exactly that "in the twinkling of an eye"23 rebirth or transformation, much like an abrupt chemical process ... as the alchemists so realized. But it must as I say be touched of adventitiously—which is the role Christ plays or did play, his work being already done. He set it in motion. It can't be turned back. He died, but he died knowing he did it. And of course he shared—he was the first to share—in the fruits of his own secret. He did add, though, that most of us would laugh at all this, finding it incredible and impossible and senseless, not to mention stupid. It never meant anything to me until March, and in March when it happened to me I couldn't relate what had happened to anything I'd ever been taught about God or religion. I thought god was up there in the sky. However, he is not; he is a spark which can fuse the total mind in each of us into something entirely new which was not there before (a description of irreversible chemical processes), burning off the dross and making stable (or as the Bible says, uncorruptible) the valuable contents. You can readily see the analogy between this and a chemical reaction in which the results are spectacular, as with ignited gunpowder. There is no way to anticipate the results based on a study of the three prior constituents, and if I told you what would happen unless you had seen it you probably wouldn't believe me. Fire is the adventitious element added; in the case of the transformation I went through, it is also a kind of fire: seen as chromatic phosphene activity. Probably this is radiation phosphene stimulation; the Soviets say that such radiation stimulating phosphene activity can come here—and does—from sidereal space. I believe it. This is the catalyst. The valuable aspect of the external catalyst is that it keeps the process within the control of who it is who controls these things; it isn't going to simply occur at a random time for no reason at all. The universal mind dispatches a Mediator—which is what Christ is called, correctly—to trigger it off; or anyhow the fish sign or any Logos triggering agent.
