RV 1.155.3
ता ईं वर्धन्ति मह्य् अस्य पौंस्यं नि मातरा नयति रेतसे भुजे । दधाति पुत्रो ऽवरम् परम् पितुर् नाम तृतीयम् अधि रोचने दिवः ॥
tā īṃ vardhanti mahy asya pauṃsyaṃ ni mātarā nayati retase bhuje | dadhāti putro 'varam param pitur nāma tṛtīyam adhi rocane divaḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
These offerings increase his mighty manly strength: he brings both Parents down to share the genial flow. He lowers, though a son, the Father's highest name; the third is that which is high in the light of heaven.
Translated by Ralph T. H. Griffith (1896)
