Mahayana Mahaparinirvana Sutra
The Nirvana Sutra or Mahāparinirvāṇa Sūtra (Chinese: Nièpán Jīng (涅槃經); Japanese: Nehankyō (涅槃経); Standard Tibetan: myang 'das kyi mdo) is one of the major sutras of Mahayana Buddhism. It shares its title with another well-known Buddhist scripture, the Mahaparinibbana Sutta of the Pali Canon but is quite different in form and content. It is therefore generally referred to by its full Sanskrit title, Mahāyāna Mahāparinirvāṇa Mahā-sūtra or more commonly simply the "Nirvana Sutra".
The Nirvana Sutra mentions some of the well-known episodes in the final months of the life of the Buddha. The sutra uses these narratives as a springboard for the expression of Mahayana ideals. Its main teachings centre on the eternity of the Buddha, the reality of the True Self, and the presence of the Buddha-dhatu (Buddha Nature) in all beings.
