Another interesting book on indigenous cultures, this book tells the story of a westerner who underwent the rituals to become a Sangoma, a Zulu medicine man. What makes this excellent is that it is easy to understand the religion of the Zulu because it is filtered through a western view yet still understood. If you enjoyed this book, I also suggest that you check out Malidoma Patrice Some's "Of Water and the Spirit" as well.
