The Three Rs - Respect (Part 1)
Most witches align themselves with the natural world in one way or another. Maybe you are in tune with the seasonal changes or the moon phases. Maybe you work with herbs or crystals or animals when crafting spells and charms. I believe that witches ought to show respect toward the natural world that we depend on for survival.
Magical Ethics: Sustainably Harvesting Plants, Rocks and Animals
Traditional magic made use of every part of the animal, plant, and mineral resources. There was not much thought to environmental consciousness that modern witches need to be aware of. Be sure to keep your conscious and common sense on alert when making decisions about which materials to use.
