Author; Aleister Crowley
777 and Other Qabalistic Writings of Aleister Crowley is a collection of papers written by Aleister Crowley. It was edited and introduced by Dr. Israel Regardie, and is a reference book based on the Hermetic Qabalah.
The Kabbalah is an early Jewish form of Torah commentary that was prominent in the sixteenth century via the book the Zohar. It introduced the diminishing Four Worlds, God as the transcendent Ain Soph, Israel as embodying the Shekinah, or "presence", as spouse of the male God, and most popularly the ten Sephiroth as schema of the universe between Israel and Jehovah. It did this by interpreting the concrete letters of the scripture rather than, say, the universal parable more evident in the gospels. Through the reformation it became popular with occultists like Heinrich Cornelius Agrippa, Pico della Mirandola and Eliphas Levi before being formalized in popular new-age magic.
