Most versions of the three-fold law state simply that whatever one does comes back to one thrice-multiplied, in amplified repercussion. Some variations ascribe up to ten-fold return, depending upon what the Witch is sending out. One short, rhymed version of the Wiccan Rede states:

"Eight words the Wiccan Rede fulfill: An it harm none, do what you will."

Please note that the term "none" is interpreted to include the doer her/himself.
