Matsya Purana — Description of Pralaya: Drying
विमानानि च दिव्यानि पुराणि विविधानि च यानि चाश्रयणीयानि तानि सर्वाणि सो ऽदहत् //
vimānāni ca divyāni purāṇi vividhāni ca yāni cāśrayaṇīyāni tāni sarvāṇi so 'dahat //
He burned up all of them—celestial vimānas, the many kinds of ancient structures, and whatever places were fit to be taken as refuge.
It depicts a pralaya-like phase where even the highest supports—divine vimānas and ancient, refuge-giving structures—are not permanent and are consumed in a sweeping destruction.
By stressing impermanence, it supports the Purāṇic ethic that rulers and householders should build merit (dharma, charity, protection of dependents) rather than rely on worldly shelters, status, or ‘secure’ possessions.
Architecturally, it underscores that even the finest ‘āśrayaṇīya’ dwellings and exalted vimāna-like edifices are transient; ritually, it reinforces the Purāṇic priority of inner refuge (dharma and devotion) over physical structures during cosmic upheaval.
