उद्गात्रे वै तथोदीचीं दक्षिणैषा विनिर्मिता

udgātre vai tathodīcīṁ dakṣiṇaiṣā vinirmitā
hayamedhe
mahā-yajñe svayam-bhū-vihite purā

udgātre vai = to the udgātā priest; tathā udīcīm = he gave the northern portion; dakṣiṇā = of dakṣiṇā; eṣā = such gifting; vinirmitā = has been prescribed; hayamedhe = Aśvamedha; mahā-yajñe = for the great sacrifice; svayam-bhū-vihite = conducted by the self-born Lord Brahmā himself; purā = which was previously.

He gave the northern portion to the Udgātā priest. Such gifting of dakṣiṇā has been prescribed for the great Aśvamedha sacrifice which was previously conducted by the self-born Lord Brahmā himself.

Such gifting of dakṣiṇā has been prescribed by the Āpastamba-sūtra and other authoritative scriptures [29]. This was originally conducted by Lord Brahmā himself quote30.
