Yangti Nakpo

The Yangti Nakpo is a cycle of Dzogchen teachings focusing on dark retreat. It was brought to Tibet by Guru Rinpoche and hidden as a terma by Yeshé Tsogyal. It was discovered by Dungtso Repa in the fourteeth century and rediscovered in the nineteenth century by Trulshik Dongak Lingpa. Therefore there are two lineages for the Yangti Nakpo: the long lineage transmission (ring gyu) from Dungtso Repa and the short lineage (nyegyü) through Trulshik Do Ngak Lingpa.
