Spirit Magick is the attracting and drawing of spirit entities fro the purpose of empowering a ritual or work of magick. Traditionaly these would be spirits of the Elemental Forces of Earth, Fire, Water, and Wir. Since these elments comprimise all of creation, it is logical to incoperate elemental spirits into formation of any desired manifestation.
Spirits from any realm can be called upon for the purpose of magick. It is important that you provide an offering to attract the spirit and an enviroment in which to draw the spirit. That is, you would not try to envoke a fire elmental in a bowl of water, or a water elemantal in a bowl of soil. If you do not have a proper enviroment for the spirit to funtion in, it will desperse. Respect, trust, and rapport are essential to successful Spirit Magick.
