त्रिभिः पवित्रैर् अपुपोद् ध्य् अर्कं हृदा मतिं ज्योतिर् अनु प्रजानन् । वर्षिष्ठं रत्नम् अकृत स्वधाभिर् आद् इद् द्यावापृथिवी पर्य् अपश्यत् ॥
tribhiḥ pavitrair apupod dhy arkaṃ hṛdā matiṃ jyotir anu prajānan | varṣiṣṭhaṃ ratnam akṛta svadhābhir ād id dyāvāpṛthivī pary apaśyat ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Bearing in mind a thought with light accordant, he purified the Sun with three refinings; By his own nature gained the highest treasure, and looked abroad over the earth and heaven.
Translated by Ralph T. H. Griffith (1896)
