Jade Eyes said it well, Kitsuzo... spirituality is not a "thing", something to sell. Of course.
People can influence others' spirits, however. Which is why a common indigenous tradition is that money is not directly involved if ceremony is guided by someone other than direct family. There is instead giveaway, a practice both practical and spiritual.
Among those traditional natives who do trade money for these things, they do so with each other, as they have the worldview to keep these things in perspective. Whatever is needed.
To those seeking - money isn't the "thing" to spend, to give... it's time. Presence. Intent. Support. So much cannot be known otherwise.
For American Indians, fullblood and mixed, presence is the factor many struggle with. Going back. Somewhat a major requirement for us. Demands of the modern clock, concern about rejection, conflict of values, these make it hard. Those seeking but raised away over a generation or more have missed so much - but it is possible, with patience...
For those not blood, but with right intent and approach... it's the same road. But naturally more complicated, to say the least. Only natural...
Another thing that's natural... I've heard it expressed by good people, in the best way... the wish that other cultures go back to their own core beliefs - so there would be some common ground. It does make good sense. It's the healing many anglo cultures will need to consider, for the sake of the earth.
But it's true and good to see that people acknowledge, sense the spirit the land holds here. There are some parallels to the spirits in others' homelands. There are also ways to understand more, without taking, without colonizing, or claiming. Many forget this but some do well also, because there is respect to what's available for them, acceptance for what is not.
Shamanism. I believe you can understand... much misperception has happened in the past, for fear and gain. So Indians are wary of labels like pagan, or shaman. The right and respect to define ourselves is a very high priority in these days, now that there is the opportunity.
Life ways that literists might insist on defining as shamanic, are far beyond that. The common ground is primal experience, within cultures, where words (or money) have no effect. Just as a Cherokee gourd dancer or Dine' roadman or Anishinaabe singer are not "shamans", still - there are common perceptions and experiences. Only different contexts, worldviews. But those can make a world of difference.
If the aversion you describe to American Indian 'shamanism' is for some spoken accounts, or published accounts on the bookshelves, good for you - your BS detector is right online. Many misrepresent, out of ego, or mere lack of understanding. You may also be picking up on the experiential aspect also - where words and money...
And if the aversion comes from deeper inside, from your own blood, I could respect that even more. Likely your own ancestors are calling.
