"I am here by the will of the Great Spirit, and by his will I am chief"

This quote by Sitting Bull speaks to the power of the Great Spirit and the function it plays in his life. It is a reminder that he is not in control of his own destiny, but rather that his life is assisted by a higher power. He acknowledges that he is chief by the will of the Great Spirit, which his position of power is not something he has earned or achieved on his own. This quote is a testimony to the power of faith and the importance of recognizing the function of a higher power in our lives. It is a pointer that we are all part of something greater than ourselves, and that our lives are directed by a force that is beyond our control. It is a reminder to be humble and to acknowledge the power of the Great Spirit in our lives.
