The Yajurveda (Sanskrit: , a tatpurusa compound of “sacrificial formula” and “knowledge”) is one of the four canonical texts of Hinduism, the Vedas. Estimated to have been mostly composed c. 1200–1000 BCE (see below), the Yajurveda Samhita, or “compilation”, contains the liturgy (mantras) needed to perform the sacrifices of the historical Vedic religion, and the added Brahmana and Śrautasutra add information on the interpretation and on the details of their performance.
