सूर्यरथ-कालचक्र-आयनविभागः, संध्योपासनम्, देवयान-पितृयानम्, विष्णुपद-गङ्गावतरणम्
विशाखानां यदा सूर्यश् चरत्य् अंशं तृतीयकम् तदा चन्द्रं विजानीयात् कृत्तिकाशिरसि स्थितम्
viśākhānāṃ yadā sūryaś caraty aṃśaṃ tṛtīyakam tadā candraṃ vijānīyāt kṛttikāśirasi sthitam
Когда Солнце проходит третью долю Вишакхи, следует знать, что Луна стоит у «главы» Криттики.
Sage Parāśara (in instruction to Maitreya)
It functions as a calendrical/astronomical indicator: a rule-of-thumb for identifying the Moon’s nakṣatra position based on the Sun’s progress, reflecting the Purana’s emphasis on measurable cosmic order.
By presenting repeatable correspondences among the luminaries, Parāśara frames time as structured and intelligible—an ordered system rather than randomness—supporting the text’s broader teaching of a governed universe.
Even when Vishnu is not named in the verse, the Purana’s cosmology treats the regular motion of the luminaries as evidence of a higher sustaining principle—Vishnu as the supreme regulator who upholds cosmic law and continuity.
