The four scriptural texts of the Hindus: Rig Veda, Sama Veda, Yajur Veda, and Atharva Veda. They are essentially a literature of chant, ritual, and recitation for vitalizing and spiritualizing all phases of man's life and activity. Among the immense texts of India, the Vedas (Sanskrit root vid, "to know") are the only writings to which no author is ascribed.
The Rig Veda assigns a celestial origin to the hymns and tells us they have come down from "ancient times," reclothed in new language. Divinely revealed from age to age to the rishis, "seers," the four Vedas are said to possess nityatva, "timeless finality."
