I found this site and like what he had to say so reposting it here:
http://www.native-languages.org/religion.htm1. Offering anything religious for sale. Money is never accepted by authentic holy people in exchange for Indian religious ceremonies like sweat lodges or sun dances, nor for religious items like medicine bags or smudged items. (They might sell arts and crafts, of course. Use your common sense--a devout Catholic might sell you a hand-carved crucifix to hang on your wall, for example, but he wouldn't sell communion wafers over the Internet or charge you admission to bring you to his church! Selling dreamcatchers or fetish carvings online is one thing, but don't believe information provided by anyone who is trying to charge people for smudging or blessing anything, making medicine, or letting them take part in a sweat lodge or dance. They are not authentic sources of information.)
2. Inviting you into their religion on their webpage. Authentic Indians may seek to educate strangers online, but actually adopting an outsider as part of their culture is only done face-to-face and after knowing the person for some time.
3. Claiming to be American Indian shamans , talking about tarot cards and Wiccan/pagan things, or talking about crystals and New Age things. I've got nothing against shamanism, paganism, or the New Age, but a cow is not a horse: none of these things are traditionally Native American. Shamanism is a Siberian mystic tradition, Wicca is a religion based in pre-Christian European traditions, Tarot readings are an Indo-European divination method, and the New Age is a syncretic belief system invented, as its name suggests, in the modern era. None of them have anything to do with authentic Indian traditions, and anyone who thinks they do is likely to be wrong about anything else he claims about Native American religions as well. Wiccans and New Agers don't have any more knowledge about actual American Indian beliefs than you do.
4. Identifying only as 'Native American' or 'American Indian' (an authentic person would list their actual tribal affiliation). Be a little wary, too, of people trying to speak with authority who identify as "mixed-blood" or "of Indian descent" or having a "Cherokee ancestor." There are certainly some mixed-blood people who were raised in their tribe's culture, but many more were not. A person who has rediscovered his Indian heritage as an adult is a seeker, not a teacher. He is not qualified to speak authoritatively about Native American religion or culture, for he wasn't raised that way and doesn't have any more knowledge about it than anyone else learning about it second-hand--including you.
If you're trying to learn about American Indian religion because you want to become a part of it, though, you not only face that problem, but another, much deeper one as well: American Indian spirituality is not
evangelistic. It is private and entirely cultural. You cannot convert to 'Native American' any more than you can convert to African-American or Korean or any other cultural identity you would need to be raised in to understand. The only way to 'join' a Native American spiritual tradition is to become a member of the cultural group, and it's impossible to do that over the Internet. No one who truly believed in American Indian spirituality would ever offer to tutor total strangers in religious matters online, much less charge anyone money for such a thing. So, by definition, the people who make these offers are those who either don't really believe in Native American spirituality, or don't know very much about it. Is that really who you want to be listening to?
Since I have put this page up, I have received many anguished emails saying "But my grandmother was part Cherokee... are you telling me to just forget that part of myself? How can I honor my Native ancestors if you won't share your religion with me?" The answer is simple: honor them the way they would want to be honored. Don't pay some new-age guru $250 to perform fake "Native American" rituals that would have offended your ancestors, go physically to their tribe and re-connect with their other descendants. It will be hard work convincing the people there that you are genuine but if you go with humility and patience you will eventually be accepted, and that is the ONLY way you will ever become part of the spiritual tradition you desire. There is no shortcut to that. Native spirituality belongs only to the cultural group, and anyone who tells you otherwise is trying to make some money off of you and/or to take a power trip at your expense.
