Matsya Purana — Lineage of the Pitṛs
त्वमस्य जगतो माता जगत्सौभाग्यदेवता दुहितृत्वं गता देवि ममानुग्रहकाम्यया //
tvamasya jagato mātā jagatsaubhāgyadevatā duhitṛtvaṃ gatā devi mamānugrahakāmyayā //
You are the Mother of this universe—the very divinity of the world’s good fortune. O Goddess, desiring to bestow your grace upon me, you have assumed the role of a daughter.
Indirectly, it presents the Goddess as the universal Mother and the source of the world’s auspicious order—implying her sovereignty over both manifestation and withdrawal, though pralaya is not explicitly described here.
It frames prosperity (saubhāgya) as rooted in divine favor and reverence for the World-Mother; for rulers and householders, it supports the Purāṇic ethic that welfare, lineage-blessings, and social stability arise from dharmic devotion and gratitude for grace.
No direct Vāstu or iconographic rule is stated, but ritually it functions as a stuti suitable for Devi-pūjā—invoking her as the giver of auspiciousness, a common prerequisite intention (saṅkalpa) for temple worship and consecratory rites.
