Here it is: the most important thing in Witchcraft. Anyone interested in witchcraft must know this. Anyone who claims to be a Witch and does not follow this principle is nothing. This is the key rule:
THE WICCAN REDE


THE WICCAN REDE

Bide by the wiccan laws we must
In perfect love and perfect trust
Live and let live
Fairly take and fairly give
Caste the circle thrice about
To keep the evil spirits out
To bind the spell every time
Let the spell be spoke in rhyme
Soft of eye and light of touch
Speak little, listen much
Deosil go by the waxing moon
Chanting out the "Witche's rune"
Widdershins go by the waning moon
Chanting out the baneful rune
When the lady's moon is new
Kiss the hand to her, times two
When the moon rides at her peak
Then your heart's desire seek
Heed the northwind's mighty gale
Lock the door and drop the sail
When the wind comes from the south
Lone will kiss thee on the mouth
When the wind blows from the west
Departed souls will have no rest
When the wind blows from the east
Expect the new and set the feast
Nine woods in the cauldron go
Burn them fast and burn them slow
Elder be the ladies tree
Burn it or cursed you'll be
When the wheel begins to turn
Let the belatane fires burn
When the wheel has turned to yule
Let the log and the horned one rules
Heed ye Flower,Nush and tree
By the lady,blessed be
Where the ripling waters go
Caste a stone and truth you'll know
When ye have a true need
Hearken not to others'greed
With a fool no season spend
Lest ye be counted as his friend
Merry meet and merry part
Bright the cheeks and warm the heart
Mind the threefold law you should
Three times bad and three times good
When the misfortune is enow
Wear the blue star on thy brow
True in love ever be
Lest thy lover's false to thee
Eight words the wiccan rede fulfill:
In it harm none, do what ye will.
