संवत्सरसुतो ह्यग्नि ऋत इत्युच्यते बुधैः / ऋतात्तु ऋतवो यस्माज्जज्ञिरे ऋतवस्ततः
saṃvatsarasuto hyagni ṛta ityucyate budhaiḥ / ṛtāttu ṛtavo yasmājjajñire ṛtavastataḥ
Agni, the son of Saṃvatsara, is called Ṛta by the wise—the sacred order. From Ṛta the seasons were born; therefore they are known as Ṛtavaḥ.
