Bolivian-born spiritual teacher, the founder of the Arica School in Chile and without doubt one of the great cornerstone founders of the spiritual enneagram.
Among his major students belong the film-maker Alejandro Jodorowsky (17 February 1929, Tocopilla, Chile), the human consciousness investigator John C. Lilly and the psychiatrist Claudio Naranjo. Lily and Jodorowsky visited him in Chile and experimented on his advise with LSD.
His student Claudio Naranjo became the founder of the psychological Enneagram. He was the teacher of contemporary enneagram guru’s like Helen Palmer, A.H. Almaas and Sandra Maitri in his named after G. (George Gurdjieff) “Seekers After Truth” (SAT) group in Berkeley, California.
The psychologist, and in her later writings with Virginia Price, an obvious astrologist, Helen Palmer (DOB unknown, she claimed according to her students to be a foundling like Moses) was one of the first person to write illuminating books about the enneagram. From 30 January 1992 till 22 July 1992, a revealing lawsuit was held between Ichazo’s Arica Institute and Helen Palmer and her publisher Harper & Row Publishers, about her undisclosed, but meant to be secret illuminations.
Arica v. Palmer, 970 F 2d 106: “The facts of this case are fully reported at 761 F.Supp. 1056 (S.D.N.Y.1991). We briefly summarize those facts most relevant to this appeal. Plaintiff-appellant Arica Institute, Inc. (“Arica”) is a not-for-profit educational institution which provides trainings based on the work of the Institute’s founder: Oscar Ichazo (“Ichazo”), himself a student of Zen, Sufism, Yoga, Buddism, Confucianism, I Ching, and the Kabbalah.”
Most interesting in this seemingly mundane document is that the A(leph) and Omega words referring to astrology, were not mentioned. But it still, reveals a lot.
