High Magic: Practical Applications of the Ancient Wisdom

"There are two forces, each having seven streams, and they again seven times seven, and so on downward unto an infinity of numbers. They are right and left, hand positive and negative, light and darkness, good and evil. Each has many names and many attrib-utes, and in the ultimate the two are one; though not yet, nor for many eons, is their oneness manifested, and until then they are opposites. Their oneness is an occult secret, difficult to understand, and it is madness for the choosers of the left hand force to meditate their treacheries when the star of the right hand force is in the ascendent." from Talbot Mundy's Queen Cleopatra
