Jnanasutra (Tibetan: ye shes mdo; 5th-6th century) is a Vajrayana Dzogchenpa who was a disciple of Sri Singha. Jnanasutra was a spiritual brother of Vimalamitra, another principal disciple of Sri Singha. Another Jnanasutra was about three centuries later.
There appear to be two Jnanasutras, with different Tibetan orthography for their names. Yeshe Do (Tibetan: ye shes mdo) flourished from the 5th - 6th centuries and was a disciple of Sri Singha, the other was a principal translator Yeshe De (Wylie: Ye shes sde; 8th-9th century), lotsawa, of the first wave of the Nyingmapa, known as the Ngagyur (Wylie: sna ’gyur), which began in the 7th century and continued until the time of Atisha.
Nomenclature, orthography and etymology
Jnanasutra (Tibetan: ye shes mdo) is sometimes rendered as Yeshe De.
In Jigme Lingpa's terma of the Ngondro of the Longchen Nyingtig he writes what approximates the phonemic Sanskrit of 'Jnanasutra' in Tibetan script as Tibetan: ཛྙཱ་ན་སཱུ་ཏྲ, Wylie: dznyA na sU tra, rather than his name in Tibetan and this comes just after a sentence to Sri Singha and before mentioning Vimalamitra.
Yeshe De (Wylie: ye shes sde; Sanskrit: Jnanasutra), a Nyingmapa, was according to Tarthang Tulku (1980) the principal 'translator' (Tibetan: lotsawa) of the first wave of translations from Sanskrit to Tibetan.
