Once we met in the dark, in secret,
"It is our choices, Harry, that show what we truly are, far more than our abilities."
2. Know the Craft.
3. Learn.
4. Use knowledge with wisdom.
5. Achieve balance.
6. Have your words in good order.
7. Have your thoughts in good order.
8. Celebrate life.
9. Live the cycles of the earth.
10. Breathe and eat properly.
11. Exercise the mind and the body.
12. Meditate.
13. Honor the Goddess and the God.
And whispered our words to the wind.
Now we can meet by the light of day
And love each other as friends.
