SIMPLE TIP: Difference between moving clockwise and counter-clockwise also known as deosil and widdershins.....
Deosil: Clockwise, the direction in which the shadow on a sundial moves as the Sun ''moves'' across the sky. Deosil is symbolic of life, positive magick, positive energies.
Widdershins: The counter-clockwise motion, usually used for negative magickal purposes, or for dispersing negative energies or conditions such as disease.
