Native Americans are very protective of their rights and customs, for obvious reasons. Whites once took their lands while trying to wipe out their culture and now spiritual starved whites are hungering for the remnants of Native American religion and culture. Some whites seek to capitalize on the need by learning Native American ceremonies and selling them to others in palatable packages, hence the new age sweat lodges.
Money has a way of spoiling everything, yet it also keeps institutions alive.
It can make things happen, but when it becomes the motive it kills the sense of spirituality especially from the perspective of Native Americans.
