Considered a madman in his English village, Adam Dilwyn Vaughan - a sin eater - was shunned by the same community who flocked to him for healing. This true tale records Ross Heaven's fascinating journey as the sin eater's apprentice, who is introduced to the lost art of sin eating and other Celtic shamanic traditions. This spiritual memoir records the author's wondrous and moving experiences with the powerful energies of the natural world. He witnesses Adam removing negative energies from a patient, meets fairy folk, reads omens in nature, discovers his soul purpose through dreaming, goes on a vision quest in a sacred cave, and participates in a sin eating ritual. Interlacing these remarkable events are Welsh legends and enlightening discussions, which shed light on these mysterious practices and invite you to see the world through the eyes of a shaman. Also included is a sin eater's workbook of the same shamanic exercises and techniques practiced by Adam.
