The Laws of Witchcraft
1) Do what you will as long as it harms none;
2) Do what you will as long as you don't interfere with anyone else's free will;
3) That which you send out returns to you threefold.
Self-explanatory and what I follow.
I also follow "Once it's done, keep your mouth shut.". Once your spell is cast or ritual done, don't talk about it.
And I believe that you shouldn't cast on anybody without their knowledge and consent (only if they ask is a good rule). You would think that would fall under #2, but some people I've met think it's okay as long as you add "And it harm none, do what you will.", "As long as it doesn't interfere with their free will.", or any other wording involving not interfering with free will. They thought it was okay because it was helping somebody, but didn't realize what could happen getting from point A to point B.
I admit that I did it once when I was a teenager while trying to help a family member. Notice that I've only ever done it ONCE!
All I'll say on it is: The spell worked, but I didn't forsee the consequences of it working. Everything's okay now, but at the time it was kind of a clusterfuck.
About Me: I'm an Aries, a Dragon, and have some Monkey in me.
Take from that what you will. And Merry Meet all!
