A Nyingma incarnation line affiliated with Katok Monastery in Kham. Although Katok Chamtruk Kunzik Jigme Dorje was identified in his time as an incarnation in the Chamtrul line, it now appears that he's considered to be the First Chamtrul, followed by the Second Chamtrul Pema Nangsel Dorje and the present Third Chamtrul Lobsang Gyatso.
