Vimalakīrti (Sanskrit:विमलvimala "stainless, undefiled" + कीर्तिkīrti "fame, glory, reputation") is the central figure in the Vimalakirti Sutra, which presents him as the ideal MahayanaBuddhistupāsaka ("lay practitioner") and a contemporary of Gautama Buddha (6th to 5th century BCE). There is no mention of him in Buddhist texts until after Nāgārjuna (1st century BCE to 2nd century CE) revived Mahayana Buddhism in India.
Vimalakīrti is characterized as a wealthy patron of Gautama Buddha. Unlike many other figures of the Mahayana literature, such as Avalokiteśvara, he is generally taken to be a historic, rather than mythic, figure and is not commonly venerated on altars nor in tantric rituals.
