"THE GREAT Magical Agent, by us termed the Astral Light, by others the soul of the earth, and designated by old chemists under the names of Azoth and MAGNESIA, this occult, unique and indubitable force, is the key of all empire, the secret of all power. It is the winged dragon of Medea, the serpent of the Edenic Mystery; it is the universal glass of visions, [...] To have control of the Great Magical Agent there are two operations necessary – to concentrate and project, or, in other words, to fix and to move."
