Chokgyur Lingpa was the "manifestation," meaning the reincarnation, of King Trisong Deutsen's son, Prince Damdzin. Another of his former lives was the great terton, Sangye Lingpa, who revealed the Lama Gongdu. Chokgyur Lingpa was the last of the 100 major tertons. He was the owner of seven transmissions and is regarded as the universal monarch of all tertons. One of the reasons for this is that no other terton has revealed a teaching that includes the Space Section (Longde) of Dzogchen. There are several Mind Section (Semde) revelations and all major tertons have revealed the Instruction Section (Mengagde), but only Chokgyur Lingpa transmitted the Space Section. This is why the Dzogchen Desum is considered the most extraordinary terma that he ever revealed.
Chokgyur Lingpa's main consort was Dechen Chodron (Lady Degah) and Padmasambhava predicted that his three children would be emanations of the three family lords: Avalokiteshvara, Manjushri and Vajrapani. I don't like saying this, for it may sound like I'm bragging about my family line, but such a prophecy does exist. The Manjushri emanation was supposed to be Wangchok Dorje, the Avalokiteshvara emanation Tsewang Norbu and the Vajrapani emanation my grandmother, Konchok Paldron.〔extract from ''Blazing Splendor'', the memoirs of Tulku Urgyen Rinpoche〕
