Matsya Purana — Saptamī Sacred Bath and the Mṛtavatsābhiṣeka Rite for Pacifying Misfortune an...
आरोग्यं भास्करादिच्छेद् धनमिच्छेद्धुताशनात् ईश्वराज्ज्ञानम् अन्विच्छेन् मोक्षम् इच्छेज्जनार्दनात् //
ārogyaṃ bhāskarādicched dhanamiccheddhutāśanāt īśvarājjñānam anvicchen mokṣam icchejjanārdanāt //
Let one seek health from Bhāskara (the Sun), wealth from Hutāśana (Agni, the Fire), knowledge from Īśvara (the Lord), and liberation (mokṣa) from Janārdana (Viṣṇu).
This verse does not address pralaya directly; it teaches a practical hierarchy of spiritual aims—worldly well-being (health, wealth), inner attainment (knowledge), and the highest goal (mokṣa) sought from Viṣṇu (Janārdana).
For a king or householder, it frames goal-oriented worship: maintain public and personal welfare (health via Sūrya), secure resources for righteous governance and charity (wealth via Agni), cultivate discernment for just rule (knowledge via Īśvara), and keep ultimate life-purpose intact (mokṣa via Janārdana).
No Vāstu or iconographic rule is stated, but it implies ritual targeting—selecting appropriate devatā-upāsanā (Sun rites, Agni offerings, devotion to Īśvara, and Viṣṇu-bhakti) according to the intended spiritual or material fruit.
