RV 10.53.3
साध्वीम् अकर् देववीतिं नो अद्य यज्ञस्य जिह्वाम् अविदाम गुह्याम् । स आयुर् आगात् सुरभिर् वसानो भद्राम् अकर् देवहूतिं नो अद्य ॥
sādhvīm akar devavītiṃ no adya yajñasya jihvām avidāma guhyām | sa āyur āgāt surabhir vasāno bhadrām akar devahūtiṃ no adya ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Now hath he made the feast of Gods effective: now have we found the secret tongue of worship. Now hath he come, sweet, robed in vital vigour, and made our calling on the Gods effective.
Translated by Ralph T. H. Griffith (1896)
