Matsya Purana — Description of Pralaya: Drying
मूत्रासृक्क्लेदम् अन्यच्च यदस्ति प्राणिषु ध्रुवम् तत्सर्वमरविन्दाक्ष आदत्ते पुरुषोत्तमः //
mūtrāsṛkkledam anyacca yadasti prāṇiṣu dhruvam tatsarvamaravindākṣa ādatte puruṣottamaḥ //
Whatever is inevitably present in living beings—urine, blood, bodily moisture, and other such impurities—all of that the lotus-eyed Supreme Person (Puruṣottama) takes upon Himself (i.e., absorbs and removes).
It presents a theological principle that the Supreme Lord (Puruṣottama) can ‘take up’ or absorb even the gross, impure constituents bound to embodied life—an idea consistent with dissolution motifs where all conditions ultimately return to the Divine.
For householders and rulers, it reinforces the ethic of cleanliness and restraint: bodily impurity is natural to embodiment, so one should practice purity (śauca), regulated living, and devotion—seeking divine purification rather than denying the body’s realities.
No direct Vāstu or iconographic rule is stated; the ritual takeaway is the emphasis on purification—supporting the logic of cleansing rites (snāna, ācamana, śuddhi) before worship, where the Lord is invoked as the remover/absorber of impurity.
