Matsya Purana — The Observance of Viśoka-Dvādaśī: A Lakṣmī–Viṣṇu Vow for Sorrow-Removal and P...
यथा देवेन रहिता न लक्ष्मीर्जायते क्वचित् तथा विशोकता मे ऽस्तु भक्तिरग्र्या च केशवे //
yathā devena rahitā na lakṣmīrjāyate kvacit tathā viśokatā me 'stu bhaktiragryā ca keśave //
Just as Lakṣmī is never born anywhere without the Lord, so may sorrowlessness be mine—and may my devotion to Keśava be supreme.
It does not describe Pralaya directly; it teaches a theological principle: auspiciousness (Lakṣmī) is inseparable from the Lord, and devotion to Keśava is sought as the means to transcend sorrow.
It frames the inner duty behind external duties: whether kingly rule or household life, one should seek divine-centered prosperity (Lakṣmī aligned with the Lord) and cultivate supreme bhakti, which steadies the mind and reduces grief amid responsibilities.
No explicit Vāstu or iconographic rule appears here; ritually, it functions as a prayer-statement (stuti/saṅkalpa) emphasizing Keśava-bhakti as the highest auspicious act.
