The Dudjom Tersar Ngöndro or Concise Recitation of the Preliminary Practices of the New Treasures of Dudjom. Is a terma practice composed and then concealed by Guru Rinpoche himself in the ninth century, the Dudjom Tersar Ngöndro was revealed by Dudjom Lingpa (1835-1904) as part of a pure vision cycle known as Daknang Yeshe Drawa. Dudjom Lingpa's incarnation, Dudjom Jigdral Yeshé Dorje (1904-1987), known to us as Dudjom Rinpoche, later expanded and clarified the text and taught it widely.
