In the words of the Dalai Lama, the purpose of religion is not to build churches and elaborate temples, but to cultivate positive human qualities such as tolerance, generosity and love. This text contains the four talks given by the Dalai Lama when he attended a meeting of Buddhist and Christian monks at Gethsemani Abbey, Kentucky. The Dalai Lama shares his understanding of four major themes explored in the meeting: the practice of prayer and meditation in the spiritual life; the stages in the process of spiritual development; the role of the teacher and the community in the spiritual life; and the spiritual goals of personal and and societal transformation. In each talk the Dalai Lama expresses the basic principles of Tibetan Buddhism and shows how they are applicable to daily practice for all spiritual seekers, regardless of their religious affiliation.
