दिन-रात, अर्धमास, तथा कला, काष्ठा और क्षण—ये काल के परिमाण हैं; इसी प्रकार पौर्णमासी, अमावस्या, तथा सिनीवाली, कुहू, राका और अनुमति भी जानने योग्य हैं।
Sage Parāśara (teaching Maitreya)
This verse treats them as formal measures within sacred time—key markers of the Moon’s cycle used to structure ritual, calendrical reckoning, and the broader cosmic order (kāla).
He lists time from larger spans (day-night, half-month) down to finer units (kalā, kāṣṭhā, kṣaṇa), then links that reckoning to lunar phases and observances, showing time as an ordered system rather than a random flow.
Even when Vishnu is not named directly, the Vishnu Purana frames kāla (time) and cosmic regularity as operating under the Supreme Reality’s sovereignty—time becomes a manifestation of divine order sustaining the universe.
