Matsya Purana — The Observance of Viśoka-Dvādaśī: A Lakṣmī–Viṣṇu Vow for Sorrow-Removal and P...
*मनुरुवाच किम् अभीष्टवियोगशोकसंघादलम् उद्धर्तुमुपोषणं व्रतं वा विभवोद्भवकारि भूतले ऽस्मिन् भवभीतेरपि सूदनं च पुंसः //

Manu said: Which observance—fasting (upoṣaṇa) or a vowed religious discipline (vrata)—can lift a man out of the crushing mass of grief caused by separation from what he desires, and which, on this earth, becomes a source of prosperity and also a destroyer of his fear of worldly existence (saṃsāra)?
This verse is not describing pralaya directly; it frames an inner, existential concern—fear of bhava (saṃsāra)—and asks which dharmic practice can destroy that fear.
Manu’s question treats fasting and vratas as practical dharma for worldly life: disciplines that can steady the mind in grief, generate merit, and support prosperity—relevant both to householders seeking stability and kings seeking righteous strength and public welfare.
The ritual significance is the emphasis on upoṣaṇa (fasting) and vrata (vowed observance) as formal religious disciplines; no Vāstu or temple-architecture rule is stated in this verse.
