When Ven. Gyatrul Rinpoche was young, he met and received transmissions from Dudjom Lingpa's speech emanation, Terton (“treasure revealer”) Kunzang Nyima, including an extensive Vajrasattva Six Bardos teaching. During that time, at Rinpoche’s request, the terton revealed a short daily version of the Vajrasattva practice, “The Mirror of Vajrasattva’s Enlightened Mind,” and entrusted it to Rinpoche as the treasure owner. However, when Rinpoche fled Tibet, he lost all contact with this profound lineage.
In 2007, Lama Chonam was able to locate a copy of Terton Kunzang Nyima’s collected works and make a connection with Tulku Theglo Rinpoche, one of Kunzang Nyima’s sons, as a lineage holder. Gyatrul Rinpoche was overjoyed to reconnect with this lineage and to find the text of the concise Vajrasattva practice. He explained that since he is the treasure owner but has not been able to practice this extensively in this life, it is important that his students and dharma centers uphold this practice, in its concise and extensive versions.
