RV 7.1.21
त्वम् अग्ने सुहवो रण्वसंदृक् सुदीती सूनो सहसो दिदीहि । मा त्वे सचा तनये नित्य आ धङ् मा वीरो अस्मन् नर्यो वि दासीत् ॥
tvam agne suhavo raṇvasaṃdṛk sudītī sūno sahaso didīhi | mā tve sacā tanaye nitya ā dhaṅ mā vīro asman naryo vi dāsīt ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Thou Agni, swift to hear, art fair of aspect: beam forth, O Son of Strength, in full effulgence. Let me not want, with thee, a son for ever: let not a manly hero ever fail us.
Translated by Ralph T. H. Griffith (1896)
