यत्किंचिदस्य दुरितं तत्क्षिप्तं वडवानले ब्रह्मा रुद्रो वसुः स्कन्दो विष्णुः शक्रो हुताशनः //
yatkiṃcidasya duritaṃ tatkṣiptaṃ vaḍavānale brahmā rudro vasuḥ skando viṣṇuḥ śakro hutāśanaḥ //
Whatever sin or misfortune may cling to him—let it be cast into the mare-faced submarine fire (Vaḍavānala). May Brahmā, Rudra, the Vasu, Skanda, Viṣṇu, Śakra (Indra), and Hutāśana (Agni) protect him.
By referencing Vaḍavānala—the cosmic submarine fire associated with consuming and dissolving impurities—the verse uses pralaya-like imagery to signify the complete burning away of sin and misfortune.
It frames ethical life as requiring regular purification: a king or householder preserves dharma not only through conduct but also through prayerful recourse to divine guardians, seeking the removal of accumulated durita (harmful karmic residue).
Ritually, it functions as a protective invocation (rakṣā/śānti) calling major deities; while not a Vāstu rule, it aligns with temple and household rites where such deity-name recitations are used for consecration and warding off inauspiciousness.
