What else is wicca good for? Well, you can change your own, down-on-this-earth reality and bring what you want into your life. There are catches. There always are. One is the common belief that what you do, good or bad, will return to you threefold. So THINK ! Another is "They" have a sense of humor. Doubt me if you like. Hey! It's a free religion. Believe what you want. (Ain't that cool also?)
You can bring love, prosperity, healing, protection, divination,or other, less 'good' things into your life or the life of others. Be prepared to accept responsibility for your actions, however.
What are your own ideas about what wicca (or magic ) is good for?
