Yudra Nyingpo, one of the 25 disciples of Guru Rinpoche

Yudra Nyingpo (Tib. གཡུ་སྒྲ་སྙིང་པོ་, Wyl. g.yu sgra snying po) — one of the twenty-five disciples of Guru Rinpoche. He was a great translator and scholar who received teachings from Vairotsana, Vimalamitra, and Guru Rinpoche. He translated many works, including the last thirteen of the eighteen texts of Semde.

Yudra Nyingpo became one of the greatest masters of Nyingma Dzogchen Semde and Longde teachings:

"Yudra Nyingpo was a prince of Gyalmo Tsawe Rong (Gyarong) in Eastern Tibet. In Gyarong, Yudra Nyingpo received teachings from Vairocana, who was exiled in the area for a certain period of time. Studying with Vairocana, Yudra Nyingpo became a great scholar and translator. Later he traveled to Central Tibet and received teachings from Guru Rinpoche and he became one of the greatest masters of semde and longde teachings of Dzogpa Chenpo in Tibet."

Yudra Nyingpo translated many works, including the 'Thirteen Later Translations' (Wylie: phyi 'gyur bcu gsum) of the 'Eighteen Major Scriptural Transmissions of the Mind Series' (Wylie: sems sde lung chen po bco brgyad):

1. Tsemo Chung-gyal (Supreme Peak) (Tibetan: རྩེ་མོ་བྱུང་རྒྱལ, Wylie: rtse mo byung rgyal)

13. Gonpa Tontrub (The Realization of the True Meaning of Meditation) (Tibetan: སྒོམ་པ་དོན་གྲུབ, Wylie: sgom pa don grub)

Liljenberg (2009: p. 51) holds that there are variances in the listing of the Thirteen Later Translations:

"The earliest lists of titles of the Thirteen Later Translations are found in the writings of the twelfth century treasure revealer Nyang Ral Nyi ma 'od zer. He gives two lists, one in his Zangs gling ma biography of Padmasambhava, and the other in his religious history, the Me tog snying po. There are significant differences between the two lists, however, and subsequent lists drawn up by various authors also show marked variations, symptomatic of continuing fluidity in the composition of this group of texts."

The current reincarnation of Yudra Nyingpo is H.E Sonam Lodre AKA Buli Trulku, the tenth reincarnation. Because of his humbleness and simplicity in this reincarnation, many people are unaware of the great translator. H.E Buli Trulku reside in far flung corner of the country near Aranachal Pradesh boarder blessing the unprivileged people which otherwise would have no blessing from any lama because of its location. Many people called Trulku the lama of unprivileged people.
I feel proud to be one of H.E Buli Trulku follower.
