यज्ञप्रवर्तनम् (Yajña-pravartana) — The Institution/Commencement of Sacrifice in Dvāpara
एतदेव तु सर्वेषां युगानां लक्षणं स्मृतम् / एषा चतुर्युगानां च गुणिता ह्येकसप्ततिः
etadeva tu sarveṣāṃ yugānāṃ lakṣaṇaṃ smṛtam / eṣā caturyugānāṃ ca guṇitā hyekasaptatiḥ
This indeed is remembered as the mark of all the yugas. And for the caturyugas, when multiplied, it is called ekasaptati—seventy-one.
