Have you really thought this all the way through? Have you thought about how native people feel about what you might want to do?
Please think about these important points before you take that fateful step and expend time, money, and emotional investment:
Native people DO NOT believe it is ethical to charge money for any ceremony or teaching. Any who charge you even a penny are NOT authentic.
Native traditionalists believe the ONLY acceptable way to transmit traditional teachings is orally and face-to-face. Any allegedly traditional teachings in books or on websites are NOT authentic.
Learning medicine ways takes decades and must be done with great caution and patience out of respect for the sacred. Any offer to teach you all you need to know in a weekend seminar or two is wishful thinking at best, fraud at worst.
