To practice magic is to be a quack; to know magic is to be a sage. - Eliphas Levi

Magic, or rather magical power, comprehends two things, a science and a force: without the force the science is nothing, or rather it is a danger.

We want to be clearly understood on this point. We are not trying to say that signs and rites are a big piece of humbug. They would be such if people did not need them; but we have to recognize that everyone has not the same degree of intelligence. Children have always had fairy stories told to them, and these stories will continue to be told as long as there are nurses and mothers. Children have faith and this is what saves them. Imagine a child of seven saying: 'I do not want to accept anything I cannot understand.' What could one teach such a monster? Accept what your teachers tell you to begin with, my fine fellow, then study it and, if you are not an idiot, you will understand it by-and-by.

The force of itself is blind, but can be directed by the will of man and is influenced by prevailing opinions. This universal fluid [the Astral Light] – if we decide to regard it as a fluid – being the common medium of all nervous organisms and the vehicle of all sensitive vibrations, establishes an actual physical solidarity between impressionable persons, and transmits from one to another the impressions of imagination and of thought."
