When her lunar orb is ceaselessly flooded by unbroken streams of water, it thereafter bears an even greater radiance—this is called upakṣaya, the waning.
Sage Parāśara (teaching Maitreya)
Speaker: Parasara
Topic: Sacred geography and the descent/course of the celestial Gaṅgā; explanation of lunar waxing/waning and the river’s cosmological mechanics
Teaching: Cosmological
Quality: authoritative
Cosmic Hierarchy: Lokas
Concept: Cosmic processes operate by ordered, intelligible cycles—here, the Moon’s ‘waning’ is explained through the purāṇic model of celestial waters affecting lunar radiance.
Vedantic Theme: Dharma
Application: Contemplate natural cycles (waxing/waning, increase/decrease) as lawful rhythms that cultivate steadiness and reverence rather than anxiety.
Vishishtadvaita: Implicitly supports a governed cosmos (niyati) under the supreme Lord’s ordinance, where even celestial change is purposeful and ordered.
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.
