RV 9.73.9
ऋतस्य तन्तुर् विततः पवित्र आ जिह्वाया अग्रे वरुणस्य मायया । धीराश् चित् तत् समिनक्षन्त आशतात्रा कर्तम् अव पदात्य् अप्रभुः ॥
ṛtasya tantur vitataḥ pavitra ā jihvāyā agre varuṇasya māyayā | dhīrāś cit tat saminakṣanta āśatātrā kartam ava padāty aprabhuḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
The thread of sacrifice spun in the cleansing sieve, on Varuna's tongue-tip, by supernatural might,- This, by their striving, have the prudent ones attained: he who hath not this power shall sink into the pit.
Translated by Ralph T. H. Griffith (1896)
