"The Source: Tshisimane is the thrilling account of surgeon David Cumes' encounter with the indigenous medicine of South Africa, his birthplace. Initiated as a sangoma or native healer, Cumes learned to integrate ancestral insights with modern medicine. I know of no more fascinating personal journey among modern medical practitioners than this--a blend of courage and wisdom that are rare in any age. Cumes is equally at home with leopards stalking his wilderness retreat, and the halls of a modern hospital. David Cumes is a modern hero--someone who has ventured into unknown territory, faced great challenges, and who returns to share his hard-earned wisdom. For anyone interested in psychological and spiritual growth, this is a must-read. But it should come with a warning: This book may change forever your idea of how the world works." Larry Dossey, M.D.
