AVŚ 8.5.19
ऐन्द्राग्नं वर्म बहुलं यद् उग्रं विश्वे देवा नातिविध्यन्ति सर्वे । तन् मे तन्वं त्रायतां सर्वतो बृहद् आयुष्मां जरदष्टिर् यथासानि ॥१९॥
aindrāgnaṃ varma bahulaṃ yad ugraṃ viśve devā nātividhyanti sarve | tan me tanvaṃ trāyatāṃ sarvato bṛhad āyuṣmāṃ jaradaṣṭir yathāsāni ||19||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Indra-and-Agni's abundant formidable defense, which not all the gods together pierce through—let that, being great, save my body on all sides, that I may be long-lived, attaining old age.
Translated by William Dwight Whitney (1905)
