In Wicca, ritual magick is BASICALLY* the invoking of the Goddess and/or the God or any manifestation thereof (Diana, Mars, Fortuna, Bast, etc). This is done for two purposes: to celebrate a holiday and to ask for Divine aid.
When celebrating a holiday (holidays for Wiccans are called "sabbats") the ritual is called an "Act of Honor." This should be fairly obvious; the Wiccan is honoring the God/dess(es) with this Ritual. This is usually done in addition to other celebration.
When asking for aid, the ritual is called a "spell" (pronounced "spell", NOT "satanic/demonic working." Just in case anyone may be confused). During this type of ritual the Wiccan asks for a boon, for him/herself or another. It could be physical healing, mental healing, protection from evil, protection from ignorance, or anything. Yes, even money. However I personally think that money should only be asked for in a true emergency, not just "I need a new Ferrari." Also, the practicioner might like to specify where the money should come from. Example: you ask for money on a tuesday and your grandmother gets hit by a car on wednesday. You'll get the money in the form of insurance, but was it worth it?
When I say "basically" it means there's a pretty good chance I'm going to be wrong about something up ahead. If you spot something incorrect, here. Push this button. Also, because Paganism is so diverse, everyone has their own way to do things. "Generally" is another word you'll see me use, it's part of this disclaimer too.
Also, love spells are BAAAAD. A spell that asks the Divine to bring your true love to you is ok, but a spell asking the Divine to make Bob/Bobette fall in love with you is dangerous! Why? Well, when they work, they deprive Bob/Bobette of his/her free will. That's definitley harming them. Expect a large karmatic backlash. Depriving a person of free will is probably the MOST harmful thing you can do to them. Possibly even beyond killing them, but I'm not sure.
And if anyone uses this site and the things therein for harmful purposes, I claim absolutley ZILCH responsibility. None. Nothing. Nada. Jack squat.
So when Bob/Bobette becomes obssesed with you and turns into a psychotic stalker, don't say I didn't warn you. And don't try to sue me, either.
