The Rev. Steed never drew any conclusions for us, but the implication was that if we can separate ourselves from our eyeballs, in the same way we can separate ourselves from the material world around us, we can realize that we are not our bodies but something else. If this sounds a lot like the mind-body dualism philosopher Rene Descartes postulated 350 years ago, Hubbard was quick to point out that Scientology is the one religion to have figured out the real truth: man's real self is neither body nor mind but spirit. And if that sounds a lot like what other religions might call a soul, Hubbard explained his difference: a thetan — the Scientology term for the spiritual essence that is each person — survives not in some nebulous Afterlife but again and again on Earth, not reincarnated as another person or another life-form but coming back as itself in a different body. Scientology is the first religion to understand death, Hubbard said.

Scientologists are not afraid of hyperbole. The Church of Scientology International, which authored "What Is Scientology?" based on the writings of Hubbard, notes that between 1970 and 1973 Hubbard made "the first significant advances on the subject of logic since ancient Greece" and that Hubbard "has become one of the most beloved men in history."

Four years before Hubbard founded the Church of Scientology he wrote a book called "Dianetics: The Modern Science of Mental Health," in which he outlined his theories of the mind, and a "technology" that can help a regular person ruled by fears, doubts and lousy communication skills progress into an enlightened person known as a "Clear."

Most people, Hubbard writes, are ruled by their "reactive" mind, which unconsciously stores mental pictures ("engrams") of distressing experiences. In a sense, says Salt Lake Scientologist Rob Magiera, these engrams act the way post-hypnotic suggestions do, commanding our subconscious to respond, in this case with fear or anger or a host of other irrational emotions. Auditing, the Rev. Parke explains, "gradiently improves a person's ability to confront" these repressed experiences and to "refile" them in what Hubbard called the "analytical mind."

Little by little, the person is helped to confront difficult experiences, starting with minor hurts (a burned finger, for example) and eventually more painful experiences, until these no longer have an effect on him, Rev. Parke explains. The full explanation of the process required many hundreds of pages in "Dianetics," he adds.

Don't confuse auditing with psychotherapy, he says. "If I go into a psychotherapist's office, they won't have a chart like this," he says, pointing to an intricate poster called "The Bridge to Total Freedom" that lists the dozens of steps between now and "Clear" and beyond, to a state Hubbard calls Operating Thetan XV. An Operating Thetan "is able to control matter, energy, space and time."
