The Yajurveda (Sanskrit यजुर्वेदः yajurveda, a tatpurusha compound of yajus "sacrificial formula', + veda "knowledge") is the third of the four canonical texts of Hinduism, the Vedas. By some, it is estimated to have been composed between 1,400 and 1000 BCE, the Yajurveda 'Samhita', or 'compilation', contains the liturgy (mantras) needed to perform the sacrifices of the religion of the Vedic period, and the added Brahmana and Shrautasutra add information on the interpretation and on the details of their performance.
