Yājñavalkya, the son of Devarāta, then vomited the mantras of the Yajur Veda and went away from there. The assembled disciples, looking greedily upon these yajur hymns, assumed the form of partridges and picked them all up. These divisions of the Yajur Veda therefore became known as the most beautiful Taittirīya-saṁhitā, the hymns collected by partridges [tittirāḥ].
