Matsya Purana — The Array of the Gods: Description of the Vaiṣṇava Host and the Lokapālas
वज्रविस्फूर्जितोद्भूतैर् विद्युदिन्द्रायुधोदितैः युक्तो बलाहकगणैः पर्वतैरिव कामगैः //

Filled with hosts of rain-clouds—born of the thunder’s crashing roar, and lit up by lightning that rises like Indra’s weapon—the sky appeared as though it were joined with mountains that move at will.
It portrays an overwhelming, ominous sky packed with thunder, lightning, and massive cloud-hosts—imagery commonly used in the Matsya Purana to signal cosmic disturbance and the approach of Pralaya-like conditions.
Indirectly, it frames a time of extraordinary natural upheaval; in Purāṇic ethics such portents imply heightened vigilance—kings ensure protection and order, while householders intensify restraint, charity, and ritual steadiness amid instability.
No direct Vāstu rule is stated; ritually, the verse functions as a portent-description—such storm-signs in Purāṇic contexts typically cue propitiatory rites to Indra and deities of rain, lightning, and protection.
