Black Yajur Veda

Along with the White Yajur Veda, one of
the two major forms of the Yajur Veda,
one of the oldest Hindu religious texts.
The major difference between these two
forms is in the placement of explanatory
notes on the Vedic mantras (sacred
sounds) and their significance. The four
recensions of the Black Yajur Veda
include these notes in the text itself. In
contrast, the one recension of the White
Yajur Veda gathers these notes into an
appendix known as a Brahmana, which
gives its name to the second major stratum of Vedic texts.
