I have had so many Ethics courses in my college studies and the hardest thing to swallow is that not everyone has Ethics.
Having a written Rede as a guideline is helpful especially when one is dabbling into something such as witchcraft. These can protect the practioner and others that a spell may affect.
I have learned that Intent has power. So in regards to the wording topic of this lesson, however you word, “And ye Harm none, so mote it be”…mean it with belief and intention. This is my belief.
