Factually, Hubbard spent the last months of the war largely as an outpatient at Oakland Naval Hospital. His chief complaint was an ulcer, though between his admission to hospital and his separation from the Navy his eyesight deteriorated markedly. This visual deterioration became part of his pension claim to the Veterans Administration.
SEX MAGICK
With his separation from the Navy, Hubbard abandoned his first wife and their two young children to take up the practice of "Magick". Hubbard had experienced a peculiar hallucination in 1938, while under nitrous oxide during a dental operation. He believed that he had died during the operation and while dead been shown a great wealth of knowledge. Upon his recovery, he wrote a book called Excalibur, but was unable to find a publisher.
Hubbard's interest in the occult also led to a brief membership in a Rosicrucian group. He told a friend that he believed himself protected by a guardian spirit whom he called "the Empress"; and he was to repeat this claim to one of his followers many years later. In 1945, Hubbard took up with Jack Parsons, head of the Pasadena lodge of Aleister Crowley's Ordo Templi Orientis.
Crowley styled himself "the Beast 666", servant of the Antichrist, and advocated the use of addictive drugs and bizarre sexual practices. Jack Parsons was a chemist and an early member of Jet Propulsion Laboratory in California, but his passion was Magick (as Crowley respelled the word). Hubbard and Parsons performed sexual ceremonies to summon a woman willing to become the mother of "Babalon", the incarnation of evil.
The affair ended with Hubbard running off not only with Parsons' girl Sara, but also with his money. Hubbard married Sara Northrup bigamously, and started to write pathetic letters applying for a war pension. In October 1947, when according to later accounts he had "cured" himself through Dianetics, Hubbard admitted to suicidal tendencies and begged for psychiatric help in a letter to the Veterans Administration.
Hubbard continued to perform black magic rituals and started to use self hypnosis, confiding to his notebook such hypnotic affirmations as "all men are my slaves". His personal papers also make it clear that he was deliberately pretending war-related ailments so that he could claim a pension increase.
