Nirvana School
The Nirvāṇa School (Chinese: 涅槃宗; Niepan-zong) was a doctrinal tradition within East Asian Mahāyāna Buddhism that centered on the interpretation and propagation of the Mahāparinirvāṇa-sūtra (Chinese: 大般涅槃經). It is characterized by a positive understanding of Nirvāṇa, and by its assertion that all sentient beings inherently possess Buddha-nature (佛性, fo xing) and so all beings can attain Buddhahood.
