Matsya Purana — The Burning of Tripura and Rudra’s Victory
विद्युन्माली च वेगेन विद्युन्माली इवाम्बुदः विद्युर्मालघनोन्नादो नन्दीश्वरमभिद्रुतः //
vidyunmālī ca vegena vidyunmālī ivāmbudaḥ vidyurmālaghanonnādo nandīśvaramabhidrutaḥ //
Vidyunmālī rushed forward with great speed—like a rain-cloud wreathed in lightning—thundering like a mass of storm-clouds as he charged straight at Nandīśvara.
It does not describe Pralaya directly; it uses storm-and-lightning imagery to convey overwhelming force and speed in a battle narrative.
Indirectly, it exemplifies Purāṇic ideals of courage and decisive action in the face of opposition—virtues later mapped onto kingly protection (rakṣaṇa) and steadfastness in dharma.
No Vāstu or ritual procedure is specified in this verse; its significance is primarily poetic—using lightning and thundercloud similes to intensify the scene.
