Matsya Purana — The Devasura War: Tumult
ह्वेषतां हयवृन्दानां रथनेमिस्वनेन च ज्याघोषेण च शूराणां तुमुलो ऽतिमहानभूत् //
hveṣatāṃ hayavṛndānāṃ rathanemisvanena ca jyāghoṣeṇa ca śūrāṇāṃ tumulo 'timahānabhūt //
From the neighing of the masses of horses, from the rumbling sound of chariot-wheels, and from the thunderous twang of warriors’ bowstrings, a vast and dreadful tumult arose.
Nothing directly—this verse is a vivid martial snapshot, emphasizing battlefield uproar rather than cosmic creation or pralaya themes.
It reflects the Kshatriya sphere of duty: organized warfare with chariots, cavalry, and archery—typical markers of royal power and the martial order expected in protection of the realm.
No Vastu or ritual procedure is stated; the technical focus is on battlefield acoustics—horse-neighing, chariot-wheel roar, and bowstring twang.
