I love Alberto Villoldo! His books are fascinating. He uses stories and exercises to illustrate what he is trying to relay. His books are very knowledgeable and his cd set kind of summarizes many of his books.His voice is so calm and pleasant, and the sincerity of what he has experienced and believes in is intriguing.The only thing I didnt care for about this set is some of it is taped during an actual conference with a public setting and in the first disc someone repeatedly clears their throat. Other parts of it are just his narration and much better than the publicly recorded sections.
