Vimalakīrti (Sanskrit: विमल vimala "stainless, undefiled" + कीर्ति kīrti "fame, glory, reputation") is the central figure in the Vimalakirti Sutra,[1] which presents him as the ideal Mahayana Buddhist upāsaka ("lay practitioner")[2] and a contemporary of Gautama Buddha (6th to 5th century BCE).[1] There is no mention of him in Buddhist texts until after Nāgārjuna (1st century BCE to 2nd century CE) revived Mahayana Buddhism in India.[3]

The Vimalakīrti Nirdeśa Sūtra characterizes Vimalakīrti as a wealthy patron of Gautama Buddha.[4] Unlike many other figures of the Mahayana literature, such as Avalokiteśvara, he is generally taken to be a historical figure like Gautama Buddha, rather than mythic or legendary, and as such Vimalakīrti is not commonly venerated on altars or in tantric rituals,[5] but as a prehistoric zen i.e. chan preacher.[citation needed]
