PrU 5.7
ऋग्भिर् एतं यजुर्भिर् अन्तरिक्षं सामभिर् यत् तत् कवयो वेदयन्ते । तम् ॐकारेणैवायतनेनान्वेति विद्वान् यत् तच् छान्तम् अजरम् अमृतम् अभयं परं चेति
ṛgbhir etaṃ yajurbhir antarikṣaṃ sāmabhir yat tat kavayo vedayante / tam oṃkāreṇaivāyatanenānveti vidvān yat tac chāntam ajaram amṛtam abhayaṃ paraṃ ceti
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Through the Rik-verses he arrives at this world, through the Yagus-verses at the sky, through the Sâman-verses at that which the poets teach,— he arrives at this by means of the Onkâra; the wise arrives at that which is at rest, free from decay, from death, from fear,— the Highest."
Translated by F. Max Müller
