The Noble Mahāyāna Sūtra “The Perfection of Wisdom in Eighteen Thousand Lines”

The Perfection of Wisdom in Eighteen Thousand Lines is one version of the Long Perfection of Wisdom sūtras that developed in South and South-Central Asia in tandem with the Eight Thousand version, probably during the first five hundred years of the Common Era. It contains many of the passages in the oldest extant Long Perfection of Wisdom text (the Gilgit manuscript in Sanskrit), and is similar in structure to the other versions of the Long Perfection of Wisdom sūtras (the One Hundred Thousand and Twenty-Five Thousand) in Tibetan in the Kangyur. While setting forth the sacred fundamental doctrines of Buddhist practice with veneration, it simultaneously exhorts the reader to reject them as an object of attachment, its recurring message being that all dharmas without exception lack any intrinsic nature. The sūtra can be divided loosely into three parts: an introductory section that sets the scene, a long central section, and three concluding chapters that consist of two important summaries of the long central section. The first of these (chapter 84) is in verse and also circulates as a separate work called The Verse Summary of the Jewel Qualities (Toh 13). The second summary is in the form of the story of Sadāprarudita and his guru Dharmodgata (chapters 85 and 86), after which the text concludes with the Buddha entrusting the work to his close companion Ānanda.
