I think you're missing the point. Curandero's work to heal sick people using specifc techniques. They are not priests telling you to believe in God, but people with skilled 'abilities', that they actually WORK with. So, like any 'job', if you want to know how they do it, it's usually easiest to learn from them. They don't go selling themselves, as much as people seek them out.

I don't understand what you're trying to say. If someone wants to understand a traditional skill, they expect it as true as possible to the original-and don't usually expect a modern day hippy twist to it. Leave traditional skills alone, for they are living history!

If you think a hippy twist is the way forward, then that's ok. But for the sake of understanding, please make it clear to people that you're screwing with a tradition, and at least try and explain why you feel you need to do this.
