Daosheng

[3] He studied in Jiankang under Zhu Fatai, and later at Lushan (Mount Lu) monastery with Huiyuan, and from 405 or 406 under Kumarajiva in Chang'an, where he stayed for some two years perfecting his education.

[5] In 408, he returned to Lushan, and in 409 back to Jiankang, where he remained for some twenty years, staying at the Qingyuan Monastery (青园寺) from 419.

[6][7][8] Daosheng's bold doctrine of including icchantikas within the purview of the Buddha-nature, even before that explicit teaching had actually been found in the long Nirvana Sutra, led to the expulsion of Daosheng from the Buddhist community in 428 or 429, and he retreated to Lushan in 430.

[9] With the availability of the long Nirvana Sutra after 430, through the translation of Dharmakshema, Daosheng was vindicated and praised for his insight.

Daosheng's exegesis of the Nirvana Sutra had an enormous influence on interpretations of the Buddha-nature in Chinese Buddhism that prepared the ground for the Chán school emerging in the 6th century.
