The shastra 'Distinguishing Consciousness and Primordial Wisdom' is an important work of Buddhist philosophy and practice written by the renowned Buddhist master Karmapa Rangjung Dorje (1284-1339). This text is one of the most important in the Kagyu tradition and helps us to understand the difference between ordinary, veiled consciousness and original wisdom. Lama Jampa Thaye will teach this according to the commentary 'The Lamp that Dispels Darkness', composed by Karma Thinley Rinpoche.
