On a visit to South Africa in 1981, Dave spent a month with the Bushmen in the Kalahari Desert. During this visit, he felt that he had finally returned to his roots and he started formulating his theory around the use of wilderness for spiritual practice. On later trips to Peru he came into contact with shamans and these meetings made him realise that the shamans had a deep knowledge of healing, that he, in spite of his medical training, was not privy to. On subsequent trips to Zimbabwe and South Africa Dave consulted various sangomas, and through the bone readings of the sangomas it was eventually revealed to him that he had been ignoring his destiny and needed to be trained or undergo thwasa. After finding an elderly Zulu mentor, Dave began his training at the beginning of 2000. During the months in training he had to undergo cleansing practices, practice bone readings, collect his own bones, connect with his ancestors and learn how to channel through the ancestors. After months of rigorous training in very basic circumstances, he returned to California as a qualified sangoma. Here he built in his garden a hut or ndumba in honour of the ancestors. He does bone readings for patients, but he remains an allopathic physician. Through dreams and bone readings it was revealed to him that he should not give up his Western practice, and that by remaining in the Western system, he believes that he is giving more credibility to the indigenous one. The book is a fascinating account of a surgeon's odyssey into the spirit world of African healing. It is the story of his initiation as a sangoma and how his life had been changed and enriched by the experience. It includes photographs of the author's training.
