From Rigpa Wiki
Apang Tertön (Wyl. a paM gter ston) aka Apang Terchen, Pawo Chöying Dorje (dpa' bo chos dbyings rdo rje) or Orgyen Trinlé Lingpa (o rgyan phrin las gling pa) (1895-1945) — a great tertön whose body could pass through solid objects and who discovered many terma teachings. He was considered to be the reincarnation of Rigdzin Gödem and one of Dudjom Lingpa's miraculously conceived sons. Apang Tertön came from Golok and his practices spread throughout Tibet.
The main holder of his teachings was his daughter Tare Lhamo (1938-2003), as well as his three sons; the custodian of his termas was Changchub Dorje. He was also a root guru of Dodrupchen Rinpoche. Sakya Trizin is his incarnation.
