Geshe Sonam Gurung received his training for the Geshe degree under the guidance of His Holiness the 33rd Menri Trizin, the Abbot of Bon Menri Monastery and lineage holder of the Yungdrung Bon spiritual tradition. Geshe Sonam served as personal assistant to His Holiness. Following the direction and continued guidance of His Holiness, Geshe Sonam and the late Dr. Daniel P Brown translated many of the key texts in the Bon Dzogchen canon. In particular, they translated significant works from Shardza Tashi Gyaltsen Rinpoche. Shardza Rinpoche’s key texts – Heart Drops of Kuntuzangpo, Kusum Rangshar; and the Treasury of the Expanse – are detailed yogic roadmaps of the Bon Dzogchen pathway to enlightenment, combining both utterly clear philosophic foundation as well as detailed practice explanation. Geshe Sonam’s goal is to make these teachings available on a global basis in forms appropriate for the 21st Century.
