Jñānayaśas (闍那耶舍, 6th century), also called Jinayaśas, was a Tripiṭaka Master from Magadha, an ancient kingdom in central India.
He went to China in the Northern Zhou Dynasty (557–81, the last of the five Northern Dynasties), together with his students Jñānagupta (闍那崛多, 523–600) and Yaśogupta (耶舍崛多, dates unknown).
In 599 or 560, the Wucheng (武成) year of Emperor Ming (北周明帝), they went to the capital city, Chang-an (長安).
They stayed at the Temple of the Four God-Kings (四天王寺) and translated Sanskrit texts into Chinese.
Jñānayaśas translated the Sūtra of Achieving a Clear Understanding of the Mahāyāna (T16n0673) in 2 fascicles, and chapter 64 of the Sūtra of Great Clouds.
He translated this chapter “Praying for Rain” twice, based on two similar Sanskrit texts.
His two translations are preserved as texts 992 and 993 (T19n0992–93). Sanskrit texts of the other chapters of this sūtra were unavailable.
