The Bodong (bo dong) tradition has a long and complicated history. The seat of what would become the institutionally independent Bodong lineage was the monastery Bodong E, which was founded in 1049 by Geshe Mudrapa Chenpo. What teachings were current there is difficult to know, save that in the twelfth century Kodrakpa Sonam Gyeltsen invited the Nepali yogin Vibhūticandra to Tibet and received from him a new transmission of the six-branch practice of the Kālacakra. Kodrakpa also propagated a lineage of Lamdre which was later subsumed into the Sakya tradition by Sonam Gyeltsen and Ngorchen Kunga Zangpo. Its greatest representative was Bodong Paṇchen Chokle Namgyel, with whom the unique Bodong Tradition is commonly said to have begun. It is important to avoid confusing Bodong Panchen with Jonang Chokle Namgyel, a teacher of Tsongkhapa and proponent of the Zhentong view.
