त्रिष्व् एतेष्व् अथ भुक्तेषु ततो वैषुवतीं गतिम् प्रयाति सविता कुर्वन्न् अहोरात्रं ततः समम्
triṣv eteṣv atha bhukteṣu tato vaiṣuvatīṃ gatim prayāti savitā kurvann ahorātraṃ tataḥ samam
When those three segments have been traversed, Savitā enters the equinoctial path; from that transition he brings about a day and a night that are perfectly equal.
Sage Parāśara (teaching Maitreya)
Speaker: Parasara
Topic: The equinoctial path (vaiṣuvatī gati) and how it yields equal day and night.
Teaching: Cosmological
Quality: authoritative
Concept: The Sun’s entry into the equinoctial course establishes perfect equality of day and night, exemplifying cosmic balance maintained by lawful motion.
Vedantic Theme: Dharma
Application: Cultivate equanimity by structuring life with balanced rhythms—work/rest, speech/silence—mirroring cosmic equilibrium.
Vishishtadvaita: Cosmic balance (samatā) reflects a purposeful, sustaining governance, consistent with the Lord as inner ruler of the world-order.
It marks the Sun’s transition into a balanced phase of motion where day and night become equal, illustrating the Purāṇic idea of cosmic order governing time.
He describes the Sun completing three prior segments of its course and then entering the equinoctial track, by which the durations of day and night are made equal.
Even when the verse speaks through astronomical imagery, the Vishnu Purana frames such regularity as the manifestation of supreme governance—Vishnu as the sustaining principle behind cosmic law and measured time.
