नष्टानिलानले लोके नष्टाकाशमहीतले केवलं गह्वरीभूते महाभूतविपर्यये //

When, in the world, wind and fire have perished, and when ether and the earth’s surface have also vanished—then, amid this reversal of the great elements, only a yawning, cavern-like void remains.
It depicts Pralaya as a collapse and reversal of the five great elements, where even wind, fire, ether, and the earth’s ground dissolve, leaving a cavernous void-like state.
By stressing the impermanence of the elemental world, it supports the Matsya Purana’s ethical thrust: rulers and householders should govern and live with detachment, uphold dharma, and invest in lasting merit (dāna, yajña, protection of subjects) rather than clinging to transient power and possessions.
No direct Vāstu or temple rule is stated; indirectly, the verse frames all material structures as impermanent under Pralaya, encouraging Vāstu and ritual works to be oriented toward dharma and consecration (puṇya) rather than mere worldly permanence.
