Matsya Purana — Inquiry into Taraka’s Slaying and the Prelude to Guha
कद्रूर्मुनिश्च लोकस्य मातरो गोषु मातरः तासां सकाशाल्लोकानां जङ्गमस्थावरात्मनाम् //
kadrūrmuniśca lokasya mātaro goṣu mātaraḥ tāsāṃ sakāśāllokānāṃ jaṅgamasthāvarātmanām //
Kadrū and the sage (Kaśyapa) are declared to be progenitors of the world; and among cattle, too, there are mother-lines. From those mothers arise the worlds of beings whose nature is both moving and unmoving.
It emphasizes creation (sṛṣṭi) through maternal lineages—beings of both moving and unmoving kinds arise from primordial mothers—rather than describing dissolution (pralaya).
By grounding society in lineage and origin, it supports dharmic responsibilities such as protecting cattle, honoring ancestors, and sustaining households through proper care of progeny and dependents.
No direct Vāstu or temple-rule is stated; the ritual takeaway is the Purāṇic stress on progenitors and mother-lines, which commonly underpins ancestor rites and lineage-based observances.
