Compassion arises naturally when one comes to perceive the lack of solid distinction between self and other. The Buddhist practice known as tonglen—in which one consciously exchanges self for other—is a skillful method for getting to that truthful perception. In this, his commentary on the renowned Tibetan lojong (mind training) text the Seven Points of Mind Training, Dzigar Kongtrul reveals tonglen to be the true heart and essence of all mind-training practices. He shows how to train the mind in a way that infuses every moment of life with uncontrived kindness toward all.
