Here is the chance, to introduce you, guys, to the explanation of the different magic practices, that we encounter a lot in modern and even black-and-white horror movies. I was listing this terminology for the research that I conducted for local web analytics company.
The best-known type of magical practice is the spell, a ritualistic formula intended to bring about a specific effect. Spells are often spoken or written or physically constructed using a particular set of ingredients. The failure of a spell to work may be attributed to many causes, such as failure to follow the exact formula, lack of magical ability or downright fraud.
Another well-known magical practice is called divination. It seeks to reveal information about the past, present or future. Varieties of divination include: Astrology, Augury, Cartomancy, Chiromancy, Dowsing, Fortune telling, Geomancy, I Ching, Omens, Scrying and Tarot.
Necromancy is another practice involving the summoning of and conversation with spirits of the dead. This is sometimes done simply to commune with deceased loved ones; it can also be done to gain information from the spirits, as a type of divination; or to command the aid of those spirits in accomplishing some goal, as part of casting a spell.
