Vyasa (; Sanskrit: व्यास, lit. 'compiler, arranger', IAST: Vyāsa) is a rishi (sage) with a prominent role in most Hindu traditions. He is also known as Veda Vyasa (Sanskrit: वेदव्यास, lit. 'the one who classified the Vedas', IAST: Vedavyāsa) or Krishna Dvaipayana (Sanskrit: कृष्णद्वैपायन, IAST: Kṛṣṇadvaipāyana). Traditionally regarded as the author of the epic Mahābhārata, Vyasa also plays a prominent role as a character. He is also regarded by the Hindu traditions to be the compiler of the mantras of the Vedas into four texts, as well as the author of the eighteen Purāṇas and the Brahma Sutras. Vyasa is regarded by many Hindus as a partial incarnation (Sanskrit: अंशावतार, IAST: Aṃśāvatāra) of Vishnu. He is one of the immortals called the Chiranjivis, held by adherents to still be alive in the current age known as the Kali Yuga. Source: Wikipedia (en)
