Describe symbolism in Lame Deer, Seeker of Visions by Richard Erdoes

The third section of the book describes, in great detail, ceremonies and rituals which continue to be practiced by the Sioux today, recounting the symbolism and importance they play in Sioux life. There is an additional short chapter on the Sioux clown, placed by itself because perhaps there was no other section in which it logically fell. The final chapter is dedicated to the origin, importance and symbolism of the unique Sioux peace pipe, made of red pipestone, found only in Minnesota. This chapter deserves to sit alone, for the pipe symbolizes the complete religion of the Sioux.
