The Third Karmapa Rangjung Dorje's unique and balanced view synthesizes Yogācāra Madhyamaka and the classical teachings on buddha nature. His work focuses on the transition from ordinary deluded consciousness to enlightened wisdom, the characteristics of buddhahood, and a buddha's enlightened activity. Included are commentaries by Jamg n Kongtrul Lodr Tay that supplement the view of the Third Karmapa on two fundamental treatises on buddha nature, emphasizing the luminous empty mind of buddha nature as presented by the great Indian masters Maitreya and Asaṅga. For those practicing the sutrayāna and the vajrayāna in the Kagy tradition, what these texts describe can be transformed into living experience.
