Bide the Wiccan Law ye must,
In perfect love and perfect trust.
Eight worlds the Wiccan Rede fulfill:
An’ye harm none, do what ye will.
What ye send forth comes back to thee
So ever mind the law of three.
Follow this with mind and heart,
Merry ye meet, and merry ye part.
These 8 lines basically summerize the Wiccan core values with our most two important laws that are recognized by all Wiccan traditions. You have the freedom to do what you want. You have the freedom to worship who and how you want. You must pay attention to the consequences of your actions and how they will impact the world around you, because you are ultimately responsible for yourself. The Law of three is simply Karma coming back to you threefold. What you put out into the world comes back to you. If you are good and kind, then you will receive good and kind in return. If you are cruel and hateful, then you will receive cruel and hateful in return. Not everyone will treat you with kindness, because they are just mean for example, but that builds on their Karma levels.
Enjoy life, help where you can, and love the world around you.
