Kapag ang bilog ng buwan niya ay laging binabaha ng tuluy-tuloy na agos ng tubig, pagkatapos ay lalo pa itong nagtataglay ng mas dakilang ningning—ito ang tinatawag na upakṣaya (pagliit).
Sage Parāśara (teaching Maitreya)
It marks the Moon’s diminishing phase as part of the cosmic time-cycle, explained through the image of the lunar orb being inundated by continuous streams, reinforcing that celestial changes follow a fixed universal order.
He presents a Purāṇic causal account: the Moon’s disc is affected by ongoing flows (vāryogha), and this process is identified as upakṣaya—one of the structured phases governing the lunar cycle.
Even when the verse discusses astronomy, the Vishnu Purana frames such cycles as operating within a divinely sustained order—time and the heavens function coherently because the Supreme Reality (Vishnu) upholds the cosmos.
