THE TREATISE OF SEXUAL ALCHEMY reveals the true meaning of the genuine documents and symbols used by the medieval alchemists, such as Paracelsus, Basil Valentine, Francis Bacon, and more, by showing how those teachings are hidden in the Egyptian Book of the Dead and the Judeo-Christian Bible."The Medieval alchemists hid the Great Arcanum among innumerable symbols and esoteric allegories. This was in order to save it from profanity, and in order for them to avoid being burned alive in the blazes of the Inquisition." -Samael Aun Weor
