If i can remember there are some paths that follow 190 laws, i myself think its a bit over done so here are the importent ones with a little of how to read them.
Wiccan Laws:
1. The complete worship of the Goddess and the God.
2. Harm ye none: Never harm yourself, another person or an animal.
3. Respect: This is for everything: the Goddess and God, people, animals, plants, yourself, EVERYTHING.
4. Balance: I think it speaks for its self.
5. Maturity: Ask yourself if you really need this spell. Make wise choices.
6. Compassion: This speaks for its self... but something to know is this goes for everything. an animal, a person (even one you dont like), every thing.
7. Wisdom: This speaks for its self.
8. Self Discipine: This speaks for its self but i can not stress this enough.
9. Perseverance: This speaks for its self.
10. Devotion: Just like rule 1 and 10. Be devoted to what you do. To the goddess, to others and to magick.
11. Purity of heart: This speaks for its self i think. But be the best person you can be and always try to better yourself.
12. Never sell Wicca (Tell others what to beleive and what not to).
13. Never try to control other people, this means love spells that are directed at a person and anything else that tries to control a persons will.
14. Dont be selfish: This speaks for its self.
15. Never sell your altar or tools: There are two ways of looking at this but the one I beleive is, never sell the magickal tools you use for anything. If you make something like a altar to sell, and you never used it or you make something for another person this is fine.
16. Accept all people as they are: Gays, people of all colors AND people of all beliefs. This is more a law to wiccans and witches.
17. Try to better yourself and be the best person you can be. This is more a law for a wiccan and witch then of magick.
18. Whatever you do, good or bad, will come back to you three fold. This doesn't just mean magick.
This isn't a rule but I am going to say it anyway. Like the name, Wiccan Knights, try to live with Honor, love in its purity and all those things that made a knight in myth.
------------------------------
Knights in history where Christian, and they weren't really all that knight like in real life. Let's just say they did the things they swore not to do.
