The Seven Hermetic Principles:

"The mastery of the seven principles is what allows one to master the “Law of Attraction”, but unfortunately, “positive thinking” is a drastic oversimplification of applying these observations of nature.
Hermeticists seek to apply these principles from the inside-out, through transmuting their baser instincts of lead into the higher intellect of gold, in order to live in harmony and balance with nature, and all who inhabit our wonderful world. However, dark Hermeticists use these principles outside-in to control and feed upon others, and to use less aware beings as pawns for their own selfish purposes."

Springmeier's "Bloodlines of the Illuminati:"
"The aim of the Society…searching out the secrets of Nature; to facilitate the study of the system of philosophy founded upon the Cabala and the doctrines of Hermes Trismegistus …" Hermes Trismegistus (as many of you know) means "the trice greatest Hermes" who was the Egyptian scribe god who is claimed to be the author of all magical writing. Hermes is credited for the grossly evil Satanic witchcraft rituals that the ancient Egyptians and modern Satanism continue to practice."
