There appear to be two Jnanasutras, with different Tibetan orthographies for their names.
The first, Wylie: ye shes mdo,[1] flourished from the 5th-6th centuries. According to Dzogchen legends, he was an early Dzogchen practitioner of Vajrayāna Buddhism and a disciple of Sri Singha. This Jnanasutra was a spiritual brother of Vimalamitra, another principal disciple of Sri Singha.[2]
According to Tarthang Tulku (1980),[3] the second Jnanasutra was the principal lotsawa (Wylie: ye shes sde) of the 8th-9th century of the first wave of translations from Sanskrit to Tibetan.[4]
In Jigme Lingpa's terma of the ngöndro of the Longchen Nyingthig he writes what approximates the phonemic Sanskrit of 'Jnanasutra' in Tibetan script as Tibetan: ཛྙཱ་ན་སཱུ་ཏྲ, Wylie: dznyā na sū tra, rather than his name in Tibetan and this comes just after a sentence to Sri Singha and before mentioning Vimalamitra.
