Keeping in the carriage his ears. I believe that the only thing that gives one a right to anything spiritual is sincerity.
Sincerity is more important than even blood.
Blood is a symbol, just like the White Buffalo is a symbol. Those of us who were born with the symbol of blood may feel more inspired to sincerely learn about the Native American traditions though they should be open to all who are sincere. Those with the symbol of blood almost have a moral obligation to learn more about the beliefs and wishes of their ancestors. We should also honor the parents of our our parents, their parents and so on. Yes, and I have a moral obligation to be so as well as Welsh, English, French, etc.
