Kṛṣṇa Yajurveda is attributed to sage Vaiśampāyana. The Saṃhitās of the Kṛṣṇa Yajurveda are made of both mantras and prose and they contain explanations of the procedures and rituals for performing Yāgas and Yajñas. There are four recensions of the Kṛṣṇa Yajurveda: Taittirīya Saṃhitā, Maitrayani Saṃhitā, Kaṭha Saṃhitā and Kapiṣṭhala Saṃhitā.
