Sidi Ahmed Dghughi is the second saint of the Hamadsha, remembered in legend as the faithful companion and disciple of Sidi Ali ben Hamdush. His domed tomb stands lower on the Zerhoun massif than his master's, at Beni Ouarad, and is the more charged of the two with the jinn world: the she-demon Aïcha Qandisha is said to haunt a grotto and spring beside it and to be bound in service to him. The branch of the brotherhood that looks to Sidi Ahmed is associated with the wildest form of the trance, the frenzy in which devotees slash their own scalps with knives, hatchets and iron balls until the blood flows, an ordeal offered to satisfy Aïcha and drawn on to heal those she has struck. Where Sidi Ali embodies the saint's serene baraka, Sidi Ahmed stands at the turbulent frontier where sainthood and possession meet.
