Witchcraft and witches in general have gotten a bad rap over the
centuries. Many people envision evil devil worshippers that sacrifice
children and animals on alters and dance naked by the moonlight.
There are two types of witchcraft, "White Witchcraft" and "Black
Witchcraft".
White witchcraft is the practice of witchcraft in which one uses
supernatural powers or magic for good. They try to bring about their
desired goals (healing, positive changes, etc.) without hurting anyone
or anything.
Black Witchcraft is the practice of witchcraft in which the witch uses
supernatural powers and magic for a desired goal in which they
intentionally try to harm someone or they don't care how their spell
affects anyone around them as long as they get what they want.
Wicca is a religion that specifically condemns the use of black magic
or witchcraft. The
Wiccan rede states that "As it harm none, do as thou wilt". What this
means is that before
you cast a spell or perform any magic, you need to be sure that the
spell you cast will not
harm anyone.
Wicca believes that everything is sacred, both animate and inanimate
objects That all powers and inspirations come from nature.. Another
important part of the Wicca belief is that whatever you send out, be
it good or evil it will come back to you three times over.
This of course is a gross simplification of the Wicca religion but, I
will say that Wicca is one of the few religions that doesn't use fear
to extort the obedience of its followers.
