Wiccan Laws
The only Laws that the Wiccans believe in are the Wiccan Rede, and the Law of Three...
Wiccan Rede:
"An it harms none, do what thou wilt"
Basically, "do what you want so long as you don't hurt anyone". This includes yourself, and referrs to anything that might be harmful to yourself or others, including drugs, violence, etc. The nice thing about the Wiccan Rede is that it leaves most of the interpretation up to you. Some people may interpret this as "don't eat meat," others may see something quite different. Basically, if you think something might hurt someone else or yourself, don't do it.
Law of Three:
All that a person gives in this life is returned three-fold; whether it be positive or negative
This is saying that anything you give out, whether it positive (kindess, generosity, etc) or negative (meaness, greediness, etc), it's returned back to you three-fold (multiplied by three).
