The Dalai Lama explains the principles of meditation in a practice-oriented format especially suited to Westerners. Based upon the middle section of the Bhavanakrama by Kamalasila, a translation of which is included, this is the most extensive commentary given by the Dalai Lama on this concise but important meditation handbook. It is a favorite text of the Dalai Lama and he often takes the opportunity to give teachings on it to audiences throughout the world. In his words, "This text can be like a key that opens the door to all other major Buddhist scriptures." Topics included are: the nature of mind, how to develop compassion and loving-kindness, calm abiding, wisdom, and how to establish a union of calm abiding and special insight.
