Saṃkhyāvarta (संख्यावर्त्त): Commencement of Yajña at the Dawn of Tretāyuga
संप्रगीथेषु सर्वेषु सामगेष्वथ सुस्वग्म् / परिक्रान्तेषु लघुषु ह्यध्वर्युवृषभेषु च
saṃpragītheṣu sarveṣu sāmageṣvatha susvagm / parikrānteṣu laghuṣu hyadhvaryuvṛṣabheṣu ca
When all the saṃpragīthas and Sāma-chants were sung in sweet measure, the swift and stalwart adhvaryus too—moving about in their rounds—were intent upon their rites.
