The Dalai Lama is one of the best-known religious leaders in the world, and one of the most respected. The Transformed Mind is a collection of talks he gave at a Tibetan Buddhist centre in Delhi during the 1990s. The history of Tibetan Buddhism is covered in a useful Introduction by Lama Thubten Zopa Rinpoche; in the transcribed talks the Dalai Lama explores many of its teachings. "The essence of Buddhist conduct and philosophy is non-violence and the theory of interdependence respectively." Non-violence has two directives: "If you can, help and serve other sentient beings; if you cannot, then at least do not harm others." Spiritual development, he says, comes from having "a good and compassionate heart [which] automatically brings inner strength and allows for less fear and less doubt." This isn't restricted to Buddhism; he has a great respect for believers in other religious traditions, and longs for greater harmony between religions. A refreshing honesty runs throughout this book, and also a delightful humour. When asked, "What is the best method to stop the population growth?" his response is "More monks and more nuns, of course! I call it non-violent birth control." One of the simplest and most useful pieces of advice in the book is that every morning we should create positive feelings by thinking, "I must have a meaningful day." Unlike his earlier book Ancient Wisdom, Modern World, this one is clearly primarily for followers of Buddhism. However, the warmth of the Dalai Lama's approach means that, though his style is sometimes discursive, his teachings are quite accessible by non-Buddhists. --David V Barrett
