Tong means “sending out” or “letting go”; len means “receiving” or “accepting.” Tonglen is ordinarily practiced in sitting meditation, using the breath. Put simply, the practitioner breathes in the bad and breathes out the good, taking on the suffering of other sentient beings. At first the practice may appear self-defeating, but as the late Chogyam Trungpa Rinpoche said, “The more negativity we take in with a sense of openness and compassion, the more goodness there is to breathe out. So there is nothing to lose.”
