Archons, Dominions and Thoughts that Run Wild
There is a simple premise in esoteric literature: thoughts have power. Even modern science accepts that behind the structure we know as the material world is a web of energy, and the interactions between different types of energy create the semblance of solidity we call matter. Thought, then, as a form of energy, has the same power. This is why in so many traditions there are admonitions about controlling the thought process, while thinking and doing are still different things, thinking does have its effects.
