Matsya Purana — Vishnu’s Names Across Yugas and the Gods’ Refuge During the Tārakāmaya War
चण्डा विद्युद्गणोपेता घोरनिर्ह्रादकारिणः अन्योन्यवेगाभिहताः प्रववुः सह मारुताः //
caṇḍā vidyudgaṇopetā ghoranirhrādakāriṇaḥ anyonyavegābhihatāḥ pravavuḥ saha mārutāḥ //
Fierce winds, accompanied by masses of lightning and producing dreadful thunderous roars, blew forth—striking one another with opposing force as they surged.
It depicts classic pralaya-portents: violent, colliding winds with lightning and terrifying thunder, signaling disorder in the elements that precedes large-scale dissolution.
Indirectly, it functions as a warning-sign motif: when nature turns chaotic, rulers and householders are urged elsewhere in the Purana to prioritize protection, ritual steadiness, and dharmic order rather than panic or adharma.
No direct Vāstu rule is stated; ritually, it reads like an inauspicious atmospheric omen (utpāta) that would prompt protective rites, recitations, and stabilizing observances described in related Purāṇic practice.
