" In the Caduceus, the two serpents are called Ob and Od. As they twine around each other, they create the magickal wand of Double Power. The Unification of the Ob and Od is picture by the globe that crowns the Caduceus. The globe which climaxes the Caduceus symbolizes the Nur Muhammadi, or Light of Mohammed, the Aur (Light) in Hebrew, which is the result of the state of equilibrium existing between the two serpent forces. This Light is the SUPREME ESSENCE. Wilhelm Reich called this serpent energy the Orgone. It has also been referred to as: Ki, Kundalini, Mana, Prana, Vril, Animal Magnetism, the Odic Force, the Astral Light, the Élan Vital, the Libido, the Atmospheric 'I' and Ether. "
