'Yudra Nyingpo' (Tibetan: གཡུ་སྒྲ་སྙིང་པོ, Wylie: g.yu sgra snying po) was one of the chief disciples of Vairotsana and one of the principal 'translators' (Tibetan: lotsawa) of the first translation stage of texts into Tibetan.
"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):

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."
