or treasure revealer of hidden teachings. Dudjom Rinpoche is considered one of the Hundred Great Tertons in the Nyingma lineage. Most terma are small in scale; major cycles are rare. Those containing many major cycles, such as Dudjom Tersar, are even rarer historically. The Dudjom Tersar is possibly the most comprehensive suite of terma to be revealed in the twentieth century. Since terma traditionally are considered to be discovered during the time they are most needed, the most recently discovered terma may be the most pertinent to current needs. Recent terma are, then, considered to "still have the warm fresh breath of the dakinis". A set of preliminary practices known as Dudjom Tersar ngöndro has to be undertaken by beginners prior to higher initiations. Dudjom Tersar contains different cycles: some are comprehensive, from beginning instruction through the highest Dzogchen teachings, and there are also smaller cycles, and individual practices, for specific purposes. There are four major cycles in the Dudjom Tersar of Dudjom Lingpa, the first three being Mind Treasures (Wylie: dgongs gter) and the last one an Earth Treasure (Wylie: sa gter): (a) The "Dagnang Yeshe Drawa" cycle (The Wisdom Nets of Pure Visions), such as the Troma teachings; (b) The "Maha-Ati Yoga Zabcho Gongpa Rangdrol" cycle (The Profound Teachings on Naturally Self-liberating Enlightened Visions), such as the teachings of Chenrezig; (c) The "Chonyid Namkhai Longdzo" cycle (the Vast Space Treasure from the Wisdom Sky of the Ultimate Nature), with teachings of Thekchod and Thodgal; and (d) The "Khandro Nyingthig" (Heart Essence of the Dakini) cycle. There are four major cycles in the Dudjom Tersar of Kyabje Dudjom Rinpoche, Jigdral Yeshe Dorje, which are all Mind Treasures (Wylie:dgongs gter): (a) The "Tsokyi Thugthig" cycle, for the practices on the outer, inner, secret and innermost secret sadhanas of the Lama; (b) The "Pudri Rekpung" cycle, for the practices of the Yidam; (c) The "Khandro Thugthig" cycle, for the practices on the outer, inner, secret and innermost secret sadhanas of the Khandro; and (d) The "Dorje Drolod" cycle. Dudjom Yangsis (Reincarnations) Yangsi (), or Tulku, is the honorific title of a young recognized reincarnation of a high lama. There are reportedly three currently known Dudjom Yangsis. The most widely know reincarnation was Kyabje Dudjom Yangsi Rinpoche, also known as Dudjom Rinpoche III, Sangye Pema Shepa, who was born on April 21, 1990, Year of the Iron Horse, in Jyekundo, Kham, Tibet,
