How Spells Work
Everything in the world emits an energy vibration of some kind, with different things having different signatures. Sometimes a signature is referred to as possessing a different level of vibration. A higher level is usually considered more spiritual and closer to the gods; a lower vibration indicates something more material. These energies reach out to touch one another, forming what amounts to a giant spider web of energy that crisscrosses around the world. It also connects the physical and nonphysical worlds. (Neo-Pagan literature refers to this as “the web.”)
As everything is connected in this fashion, it is possible to have an effect on things simply by twitching the web in one place and allowing the resulting vibration to flow along the web until it reaches your goal. The web is also how we can send energy to someone or something far away from us—the strands of energy that connect all organic and living things serve as wires through which we can send our energy.
