"In this book it is spoken of the Sephiroth and the Paths; of Spirits and Conjurations; of Gods, Spheres, Planes, and many other things which may or may not exist.

“And Her Concoction shall be sweet in our mixed mouths, the Sacrament that giveth thanks to Aiwaz, our Lord God the Devil, that He hath fused His Beast's soul with His Scarlet Whore's, to be One Soul completed, that It may set His image in the Temple of Man, and thrust His Will's rod over them and rule them. And that imperléd sea, dark with that oozy shore-mud which it washed, shall wash us, body and mind, of all that is not He, moisten our throats and loosen our loud Song of praise, Thanksgiving unto Him.”

“Intolerance is evidence of impotence.”

“The discovery of radioactivity created a momentary chaos in chemistry and physics; but it soon led to a fuller interpretation of the old ideas. It dispersed many difficulties, harmonized many discords, and — yea, more! It shewed the substance of Universe as a simplicity of Light and Life, manners to compose atoms, themselves capable of deeper self-realization through fresh complexities and organizations, each with its own peculiar powers and pleasures, each pursuing its path through the world where all things are possible.”
