Brahmanas

With creation
The Brahmanas (/ˈbrɑːmənəz/; Sanskrit: ब्राह्मणम्, Brāhmaṇam) are Vedic śruti works attached to the Samhitas (hymns and mantras) of the Rig, Sama, Yajur, and Atharva Vedas. They are a secondary layer or classification of Sanskrit texts embedded within each Veda, which explain and instruct on the performance of Vedic rituals (in which the related Samhitas are recited)
