Matsya Purana — The Battle for Tripura: Portents
हरः प्राप्त इतीवोक्त्वा बलिनस्ते महासुराः आजग्मुः परमं क्षोभम् अत्ययेष्विव सागराः //
haraḥ prāpta itīvoktvā balinaste mahāsurāḥ ājagmuḥ paramaṃ kṣobham atyayeṣviva sāgarāḥ //
Saying, as it were, “Hara (Śiva) has arrived!”, those mighty great Asuras were seized by extreme agitation—like the oceans when the time of upheaval has come.
It uses Pralaya-like imagery—oceans churning at a catastrophic “end-time”—to convey the Asuras’ violent inner upheaval, linking emotional turmoil to cosmic dissolution symbolism.
Indirectly, it functions as an ethical warning: uncontrolled kṣobha (agitation) leads to disorder; the king/householder is urged elsewhere in the Matsya Purana to cultivate steadiness and restraint to prevent social ‘ocean-like’ upheaval.
No direct Vāstu or ritual rule appears; the verse is primarily poetic and cosmological, using the ocean-at-crisis simile rather than prescribing temple-building or rite procedures.
