Located in Lithang in Kham, this cave is the treasure site of Longsel Nyingpo's fourth cycle of treasures. It's likely also the treasure site called Dagam Wangpuk in the Terlung valley, which is a treasure site of Jamgon Kongtrul. Chokgyur Lingpa assisted in the cave's consecration with Jamgon Kongtrul around 1854, and he recorded receiving his sole pure vision revelation, the Bima lhadrub (bima lha sgrub), at that time.
