Yajurveda is the Veda of yajana or worship. It refers to acts of worship such as oblations made into Agni or Fire. It has two branches, Krishna or Black and Shukla or White. While both contain mantras or incantations to be chanted at rituals, Black Yajurveda also has many explanations. The recensions of Black Yajurveda are Taittirya, Katthaka, Maitrayani and Kapishtthala. Those of White Yajurveda are Madhyanadina and Kanva. The literary value of Yajurveda is mostly for its prose, which consists of short terse sentences full of meaning and cadence.
