Entrance into the Old Ways begins with the pricking of a finger with a rose thorn, which produces a drop of blood. This opens the way into the Thorned Path, a system, which uses five rose thorns to symbolize the five arts of Witchcraft that one should master. These arts are Herbalist, Fortune-Teller, Spirit Medium, Mystic, and Magician. We call mastering these aspects 'the gathered thorns' --thus the Thorned Path.
