AVŚ 19.22.21
ब्रह्मज्येष्ठा सम्भृता विर्याणि ब्रह्माग्रे ज्येष्ठं दिवम् आ ततान । भूतानां ब्रह्मा प्रथमोत जज्ञे तेनार्हति ब्रह्मणा स्पर्धितुं कः ॥२१॥
brahmajyeṣṭhā sambhṛtā viryāṇi brahmāgre jyeṣṭhaṃ divam ā tatāna | bhūtānāṃ brahmā prathamota jajñe tenārhati brahmaṇā spardhituṃ kaḥ ||21||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Heroisms [were] gathered with the bráhman as chief; the bráhman as chief in the beginning stretched the sky; the Brahman was born as first of creatures; therefore (téna) who is fit to contend with the Brahman?
Translated by William Dwight Whitney (1905)
