Matsya Purana — The Observance of Ananta-Tritiya
यथा न देवि देवेशस् त्वां परित्यज्य गच्छति तथा माम् उद्धराशेषदुःखसंसारसागरात् //
yathā na devi deveśas tvāṃ parityajya gacchati tathā mām uddharāśeṣaduḥkhasaṃsārasāgarāt //
O Goddess, just as the Lord of the gods never departs by abandoning you, so too rescue me from the ocean of saṃsāra, filled with unending sorrow.
It does not describe cosmic creation or pralaya directly; instead it uses the metaphor of the “ocean of saṃsāra” to express existential peril and the need for divine deliverance.
It frames the inner foundation of dharma: even while fulfilling royal or household duties, one should cultivate śaraṇāgati (seeking refuge) and remember that worldly life brings duḥkha unless guided by devotion and spiritual aim.
No Vāstu/temple-building rule is stated; the ritual takeaway is devotional—recitation as part of Devī-stuti and prayer for protection and liberation.
