The ideas presented here are theories and ideas. Proof of the truth of said I leave in the hands of the practioner.
Aleister Crowley defines magick as "The science and art of causeing change to occur in conformity with will."
THEORY: Magick is the utilization of the natural energy present in the universe to bring about ones will.
I came across this basic exercise in Christopher Penczak's Inner Temple of Witchcraft.
Hold your hands about three feet apart, palms faceing each other. Allow the experience to happen naturally. Bring your hands closer together slowly. Be aware of the sensation. Notice any feelings that come in waves or layers. These are the levels of your aura. Rub hands together if needed to increase sensitivity of the hands. When finished wipe your hands together as if wiping away water or dirt. This removes excess energy left behind.
This is said to be your bodies translation of the energy feel generated by your body. I myself believe that the energy flows through us and is not generated by us but that's me. Sceptics will have a field day with this one.
