Vyasa occupies a singular place in Hindu tradition as the figure to whom an enormous share of the sacred literature is attributed. His name, Vyasa, means "the arranger" or "compiler," and he is credited with dividing the primordial Veda into its four collections (Rig, Yajur, Sama, Atharva) for transmission, for which he bears the title Veda Vyasa. He is also traditionally named as the author of the vast epic Mahabharata, and, unusually, appears within it as a character: the grandfather of both sets of warring cousins, who intervenes at key moments and to whom the poem's composition is ascribed.
Tradition further assigns to him the eighteen major Puranas and the Brahma Sutras, the foundational text of Vedanta philosophy. Modern scholarship treats "Vyasa" less as a single historical individual than as a traditional attribution, a name under which a long, collective process of composition and redaction was gathered and given a single revered author. In that sense he is the personification of the tradition's own textual memory: the sage who stands for the gathering, ordering, and handing-down of the sacred word. He is counted among the chiranjivi, the immortals said to remain present through the ages.
