The Eleven Satanic Rules of the Earth- LaVeyan Satanism

1.Do not give opinions or advice unless you are asked.
2.Do not tell your troubles to others unless you are sure they want to hear them.
3.When in another’s home, show them respect or else do not go there.
4.If a guest in your home annoys you, treat them cruelly and without mercy.
5.Do not make sexual advances unless you are given the mating signal.
6.Do not take that which does not belong to you, unless it is a burden to the other person and they cry out to be relieved.
7.Acknowledge the power of magic if you have employed it successfully to obtain your desires. If you deny the power of magic after having called upon it with success, you will lose all you have obtained.
8.Do not complain about anything to which you need not subject yourself.
9.Do not harm young children.
10.Do not kill non-human animals unless you are attacked or for your food.
11.When walking in open territory, bother no one. If someone bothers you, ask them to stop. If they do not stop, destroy them.
