Matsya Purana — The Attendant Hosts of the Sun and Moon: Monthly Gaṇas
भूतानामशुभं सर्वं व्यपोहति स्वतेजसा मानवानां शुभैर्ह्येतैर् ह्रियते दुरितं तु वै //
bhūtānāmaśubhaṃ sarvaṃ vyapohati svatejasā mānavānāṃ śubhairhyetair hriyate duritaṃ tu vai //
By its own radiant power it drives away every inauspiciousness afflicting living beings; and for human beings, indeed, by these auspicious influences their sin and misfortune are carried off.
It reflects the Pralaya-era theology that divine tejas (radiant potency) protects beings by dispelling inauspicious forces, emphasizing preservation amid cosmic instability rather than describing mechanics of dissolution.
It supports the dharmic duty to maintain śubha (auspicious order) through righteous conduct and approved rites—removing durita from oneself and one’s community, a key responsibility for householders and rulers in Purāṇic ethics.
While not naming a specific Vāstu rule, it highlights the ritual principle that śubha observances (purificatory, protective, auspicious acts) are intended to dispel aśubha—an idea foundational to consecrations and protective rites used in temple/space sanctification.
