Saṃkhyāvarta (संख्यावर्त्त): Commencement of Yajña at the Dawn of Tretāyuga
तस्माद्विशिष्यते यज्ञात्तपः सर्वैस्तु कारणः / ब्रह्मणा तपसा सृष्टं जगद्विश्वमिदं पुरा
tasmādviśiṣyate yajñāttapaḥ sarvaistu kāraṇaḥ / brahmaṇā tapasā sṛṣṭaṃ jagadviśvamidaṃ purā
Therefore austerity surpasses sacrifice, for it is the cause of all. In ancient times Brahmā created this entire universe by austerity.
