Matsya Purana — Cosmic Creation: Emergence of the Great Elements and the Navel-Lotus
ततः संशोषयामास पावकः सलिलं बहु क्षयाज्जलनिधेश्छिद्रम् अभवद्विस्तृतं नभः //
tataḥ saṃśoṣayāmāsa pāvakaḥ salilaṃ bahu kṣayājjalanidheśchidram abhavadvistṛtaṃ nabhaḥ //
Then the Fire (the cosmic heat) dried up vast quantities of water; as the ocean’s mass diminished, a great opening appeared in the sea, and the sky seemed to spread wide and unobstructed.
It depicts a pralaya-like condition where cosmic fire (Agni) evaporates the waters, the ocean shrinks, and a vast “breach” appears—classic imagery of dissolution through heat and desiccation.
Indirectly, it underscores impermanence: rulers and householders are urged elsewhere in the Matsya Purana to govern and live dharmically, knowing worldly stability (even oceans) can be undone by time and cosmic cycles.
No direct Vastu or ritual rule is stated; however, the verse supports a common Purāṇic ritual theme—recognizing cosmic cycles (pralaya) as a backdrop for rites, vows, and temple culture that aim at enduring merit beyond physical change.
