RV 10.39.1
यो वाम् परिज्मा सुवृद् अश्विना रथो दोषाम् उषासो हव्यो हविष्मता । शश्वत्तमासस् तम् उ वाम् इदं वयम् पितुर् न नाम सुहवं हवामहे ॥
yo vām parijmā suvṛd aśvinā ratho doṣām uṣāso havyo haviṣmatā | śaśvattamāsas tam u vām idaṃ vayam pitur na nāma suhavaṃ havāmahe ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
As 'twere the name of father, easy to invoke, we all assembled here invoke this Car of yours, Asvins, your swiftly-rolling circumambient Car which he who worships must invoke at eve and dawn.
Translated by Ralph T. H. Griffith (1896)
