The Goetia: The Lesser Key Of Solomon
The Seals of the Goetia are the name and sigils of a certain set of spirits, angels and demons, both good and evil. The magician uses these seals along with ritual magic to obtain control over the power of these spirits and to cause them to do their bidding. This practice is referred to as low magick, or magick that is used to deal with everyday tasks, problems and concerns (this does not make low magick a bad thing, however). Caution should always be used when dealing with the inhabitants of the spirit world.
