The Jewels of the Heart series is a collection of classic short teachings by H.E. Chagdud Tulku Rinpoche.
Out of great love for his students, Chagdud Rinpoche left behind these sublime markers so that they could be used as a precise method to check our own minds.
This is a classic 14th century Tibetan Buddhist text traditionally studied in order to train in the compassionate wisdom of a bodhisattva.
