Occasionally, witches and spiritualists from the so-called "White Light" path like to label and criticize others decisions or life choices. They argue that manipulative - or what they refer to as 'black magick' - is wrong. Hint: the Law of 3 is an entirely made up concept. It it nothing more than 1950's paganism, propagated by miserable new age books.
Do you think energetic or emotional manipulation in black magick? All magick, all physical action, and the very act of breathing is in itself manipulation. You manipulate energy, you manipulate air, you physically manipulate the real-world experience around you -- and that's true even without magick!
Cursing and healing. Left hand path and right hand path. Black and white. Desiring and repelling. They are all part of the same circle. All interlocking forms of spiritual, magickal and transformational work. Human energies in the spiritual, coming into the material world through perfectly natural means.
