एकप्रमाणम् एवैष मार्गं याति दिवाकरः अहोरात्रेण यो भुङ्क्ते समस्ता राशयो द्विज
ekapramāṇam evaiṣa mārgaṃ yāti divākaraḥ ahorātreṇa yo bhuṅkte samastā rāśayo dvija
الشمسُ حاملةُ النهار تسير في طريق واحد ذي مقدارٍ معلوم. أيها الثنائيّ الميلاد، في يومٍ وليلةٍ واحدة تجتاز—كأنها «تلتهم»—جميع بروج الفلك على الترتيب.
Sage Parāśara (teaching Maitreya)
It highlights a fixed cosmic order: the Sun’s regular motion becomes the dependable standard by which time (day-night and larger cycles) is recognized and maintained.
By linking ahorātra (a full day-night) to the Sun’s traversal of the rāśis, Parāśara frames time as an observable rhythm rooted in the heavens’ regulated movement.
Even when Vishnu is not named in the verse, the Purāṇic worldview treats such orderly celestial functioning as operating under the Supreme Reality’s governance—Vishnu as the sustaining principle of universal law.
