यदा चन्द्रश् च सूर्यश् च यदा तिष्यबृहस्पती एकराशौ समेष्यन्ति भविष्यति तदा कृतम्
yadā candraś ca sūryaś ca yadā tiṣyabṛhaspatī ekarāśau sameṣyanti bhaviṣyati tadā kṛtam
यदा चन्द्रश्च सूर्यश्च यदा तिष्यबृहस्पती । एकराशौ समेष्यन्ति भविष्यति तदा कृतम् ॥
Sage Parāśara (in dialogue with Maitreya)
This verse uses a convergence of the Sun, Moon, Tiṣya, and Bṛhaspati as a time-marker indicating the return of Kṛta (Satya) Yuga, showing that cosmic order and moral ages are linked to sacred time.
Parāśara frames yuga transition as cyclical and law-governed: when specific celestial conditions align, the age of truth (Kṛta) arises again, implying an ordained rhythm to decline and restoration.
Even when the verse speaks through astronomical signs, the Purana’s underlying claim is that Vishnu, as the Supreme regulator of time and dharma, ensures the world’s renewal and the re-establishment of harmony in Kṛta Yuga.
