RV 7.87.6
अव सिन्धुं वरुणो द्यौर् इव स्थाद् द्रप्सो न श्वेतो मृगस् तुविष्मान् । गम्भीरशंसो रजसो विमानः सुपारक्षत्रः सतो अस्य राजा ॥
ava sindhuṃ varuṇo dyaur iva sthād drapso na śveto mṛgas tuviṣmān | gambhīraśaṃso rajaso vimānaḥ supārakṣatraḥ sato asya rājā ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Like Varuna from heaven he sinks in Sindhu, like a white-shining spark, a strong wild creature. Ruling in depths and meting out the region, great saving power hath he, this world's Controller.
Translated by Ralph T. H. Griffith (1896)
