206.13

phalairarghyaṃ pradāsyāmi gṛhāṇārghyaṃ mahāmune /
agastya evaṃ khanamānaḥ khanitraiḥ prajāmapatyaṃbalamīhamānaḥ /
ubhau karṇāvṛṣirugratejāḥ pupoṣa satyā deveṣvāśiṣojagāma //

I shall grant the water offering with fruits; accept the water offering, O great sage! / Thus Agastya, digging with spades, desiring progeny, offspring, and strength, / the sage of fierce splendor nourished both varnas; true among the gods, he attained their blessings.’
