Both historically, as the famous cup that passed through the hands of Jesus of Nazareth, and symbolically, as the sacred, symbolic vessel of the Mysteries, Samael Aun Weor wrote extensively about the Grail. Notable chapters are to be found in The Great Rebellion and The Three Mountains. As a symbol, the cup represents both the woman and her sexual organs, just as the Spear or Lance represents the man or phallus.
