RV 7.88.4
वसिष्ठं ह वरुणो नाव्य् आधाद् ऋषिं चकार स्वपा महोभिः । स्तोतारं विप्रः सुदिनत्वे अह्नां यान् नु द्यावस् ततनन् याद् उषासः ॥
vasiṣṭhaṃ ha varuṇo nāvy ādhād ṛṣiṃ cakāra svapā mahobhiḥ | stotāraṃ vipraḥ sudinatve ahnāṃ yān nu dyāvas tatanan yād uṣāsaḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Varuna placed Vasistha in the vessel, and deftly with his night made him a Rsi. When days shone bright the Sage made him a singer, while the heavens broadened and the Dawns were lengthened.
Translated by Ralph T. H. Griffith (1896)
