The Aquarian Foundation was a Spiritualist church built around the mediumship of its founder Rev. Keith Milton Rhinehart. It was founded in 1955 and existed for several decades as a single congregation in Seattle. Rhinehart articulated an eclectic occult perspective that combined elements of Theosophy and Eastern religion with more traditional Spiritualism. Rhinehart also claimed contact with the ascended masters identified with the Theosophical Society. Through the 1960s Rhinehart gained some fame as a "materialization" medium. In the 1970s his ideas began to spread across the United States and into Canada. Rhinehart claimed to possess the stigmata, the extraordinary appearance of the wounds of Christ, which appeared on his body and were seen by many.
The work of the Aquarian Foundation centered upon contact with the ascended masters, who constituted the Great Brotherhood of Cosmic Light (termed by some the Great White Brotherhood ), the spiritual hierarchy that mediates divine energies to humanity. Many of the sessions during which Rhinehart channeled messages from the masters have been recorded, transcribed, printed, and were distributed to the foundations's various centers.
The brotherhood affirmed a belief in karma and reincarnation, the evolution of the soul, the law of cause and effect, and the eventual attainment of personal mastery. Among those contacted by Rhinehart were Saint Germain, Master Morya, Sanat Kumara, and Djual Khul (all prominent figures in Theosophy and the I Am Movement ). Also included among the masters were the Angel Moroni (the angel who gave the Book of Mormon to Joseph Smith Jr.), Mahatma Ghandi, and flying saucer entities Clarion and Ashtar. The foundation's last known address was 315 15th Ave. E., Seattle, WA 98112.
