Many tribes here in the USA all have their own way of doing Pipe Ceremony. Also there was a time when the Lakota did not want white people to be Pipe Carriers - I was crushed - went to a friend of mine with First Nations in Canada - he told me they were not referring to me. It was more about the ones doing it for money and fame. I was reassured I could continue. Great Spirit never told me I could not lead the ceremonies ....so I continued and still carry the Sacred Community Pipe. Also one of my teachings from Brooke Medicine Eagle was most of the Holy people of the tribes were killed and many traditions lost. We also must allow for Spirit to come join us for the Ceremony and when that flow begins - the good stuff follows.
