The best way to test the resolve of your fellow cultists is by making them commit to very rigorous rules that affect their life significantly.

I mean if you can get them to cut of a piece of their reproductive organs, you have insanely loyal followers. Also resisting something to eat that is very tasty, of it said ‘don’t eat shit’ it’s not a very hard rule to follow.

Somehow this works like a drug for some people. There a reason that many rehabs are ran by religious fellows.
