Matsya Purana — Uma’s Austerities and the Slaying of the Deceiver Asura ĀḌi
सा चास्यै सर्वमाचख्यौ शंकरात्कोपकारणम् पुनश्चोवाच गिरिजा देवतां मातृसंमताम् //
sā cāsyai sarvamācakhyau śaṃkarātkopakāraṇam punaścovāca girijā devatāṃ mātṛsaṃmatām //
She told her everything—the cause of Śaṅkara’s anger. Then Girijā spoke again, indicating the Goddess approved by the Mothers (the Matṛs).
This verse does not discuss Pralaya; it focuses on a Shaiva narrative moment—explaining the cause of Śiva’s anger and indicating a Goddess sanctioned by the Matṛs.
Indirectly, it reflects an ethical principle found across the Matsya Purana: conflicts (even divine anger) are addressed by clearly stating causes and following approved religious authority—analogous to a king or householder resolving disputes through proper counsel and sanctioned practice.
The ritual takeaway is authority and legitimacy: worship or invocation of a devatā is framed as “Matṛ-approved,” implying correct lineage/authorization in rites rather than any specific Vāstu or temple-building rule in this verse.
