Nyagla Pema Dudul (1816–1872) was a Nyingma treasure revealer from Nyarong in eastern Tibet. Born into a once-wealthy family that fell into hardship—in a story his biographers explicitly compare to that of Milarepa — his early life was marked by loss, poverty, and illness. He trained with many of the leading masters of his time, among them Do Khyentse Yeshe Dorje, Dza Patrul Rinpoche, the Fourth Dzogchen Drubwang Mingyur Namkhai Dorje, and the First Tsopu Drubchen Choying Rangdrol—whose teachings proved particularly transformative, inspiring Pema Dudul to dedicate his life entirely to yogic practice. He undertook long periods of solitary retreat, during which he revealed a number of treasures, including a spectacular public revelation from a large rock witnessed by his assembled disciples. Renowned as a yogin, teacher, and composer of songs of realisation—collected in a dedicated mgur 'bum—he was also known for his radical generosity and non-attachment, routinely crushing precious offerings and distributing wealth to beggars. His students included some of the most celebrated masters of the following generation: the terton Lerab Lingpa, the Dzogchen master Adzom Drukpa Drodul Pawo Dorje, and the yoginī A-gyu Khandro Dorje Peldron, to whom he transmitted the Longsel Dorje Nyingpo and instructions for the Yangti Nakpo dark retreat. According to tradition, he attained the rainbow body at the time of his passing, said to be the last of the hundred thousand yogins of Katok to do so.
