Matsya Purana — Description of Pralaya: Drying
वायुनाक्रम्यमाणासु द्रुमशाखासु चाश्रितः तेषां संघर्षणोद्भूतः पावकः शतधा ज्वलन् //
vāyunākramyamāṇāsu drumaśākhāsu cāśritaḥ teṣāṃ saṃgharṣaṇodbhūtaḥ pāvakaḥ śatadhā jvalan //
When the branches of trees are lashed and driven by the wind, fire—born from their mutual friction—arises and blazes forth in a hundred flames.
It highlights how intensified wind can generate destructive fire through friction—an image used in Purāṇic cosmology to explain cascading elemental forces during upheaval and dissolution.
As an ethical analogy, it warns that unchecked forces (like anger, conflict, or poor governance) can ‘ignite’ widespread harm; a ruler or householder must prevent conditions that lead to destructive escalation.
It underscores the practical and symbolic need to manage vāyu (airflow) and agni (fire risk)—a principle later echoed in Vastu-oriented concerns like ventilation, hearth placement, and fire-safety in ritual spaces.
