It’s pretty simple, really. First they have to complete Boukoloi (literally “ox-tender”) training (which consists of the material found in Tending the Bull: A tradition of Dionysian devotion, Masks of Dionysos: Getting to Know the God Through His Heroes and Heroines, Hunting Wisdom: A Bacchic Orphic Diviner’s Manual and Spirits of Initiation: A Study of the Toys of Dionysos, as well as a bunch of one-on-one training covering stuff not contained in the books.) They must receive their Toys initiation. And they must develop a strain of the tradition, which they are then responsible for cultivating and bringing others into. I’m condensing a lot into “one-on-one training” but that’s the gist of it. The whole process generally takes two to five years, and there are initiations and empowerments that must be performed in person.
