Yajur Veda (Skt.). The Vedic collection of sacrificial prayers (yajus) used by the Adhvaryu priest. Of the four Vedas, it most reflects the Vedic sacrifice in its ritual character and full scope. The Yajur Veda has two major divisions: the Black Yajur Veda existing in four versions and the White Yajur Veda existing in two versions. The titles appear to have arisen as polemical terms used by the followers of the White school to characterize the purity of their tradition. Keith estimated the recension of the Black Yajur Veda at not later than 600 BCE.
