RV 10.71.11
ऋचां त्वः पोषम् आस्ते पुपुष्वान् गायत्रं त्वो गायति शक्वरीषु । ब्रह्मा त्वो वदति जातविद्यां यज्ञस्य मात्रां वि मिमीत उ त्वः ॥
ṛcāṃ tvaḥ poṣam āste pupuṣvān gāyatraṃ tvo gāyati śakvarīṣu | brahmā tvo vadati jātavidyāṃ yajñasya mātrāṃ vi mimīta u tvaḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
One plies his constant task reciting verses. one sings the holy psalm in Sakvari measures. One more, the Brahman, tells the lore of being, and one lays down the rules of sacrificing.
Translated by Ralph T. H. Griffith (1896)
