“There are many schools of magic in existence today, but many of them ultimately derive from the same source and almost all of them share the same four fundamental theoretical assumptions:
1. That the universe of the physical scientist is only a part, and by no means the most important part, of total reality.
2. That human will-power is a real force, capable of being trained and concentrated, and that the disciplined will is capable of changing its environment and producing supernormal effects.
3. That this will-power must be directed by the imagination.
4. That the universe is not a mixture of chance factors and influences but an ordered system of correspondences, and that the understanding of the pattern of correspondences enables the occultist to use them for his own purposes, good or ill”.
-Francis King, “Techniques of High Magic”
