You hold in your hands one of the finest books ever published on the Kadam tradition of Tibetan Buddhism, whose basic program of "mind training" (lojong) was adopted by every Tibetan order. The two long poems translated here, attributed to Atiśa's guru, Dharmarakṣita, are among the oldest and most dramatic of the mind-training texts, full of vivid imagery, sutra and tantra practices, and both conventional and ultimate perspectives on the world.
