Dharmapa, Doctrine (19th), was a direct disciple of Dudjom Lingpa. In a vision, Dudjom Lingpa was told by Yeshe Tsogyal that Dharmapa was a reincarnation of Sengé Gyatso, himself a student of Trengpo Tertön Sherab Özer (1518-1572/84). Dharmapa was also a reincarnation of Pema Ozer, Lotus Light Rays, a direct student of Rigdzin Düddul Dorje (1615-1672), a previous incarnation of Dudjom Lingpa. Dharmapa requested Dudjom Lingpa to transcribe a sadhana of Tröma Nakmo.
