Matsya Purana — Lineage of the Pitṛs
उपसंहारकृद्रुद्रस् तेनामङ्गलभागयम् चुकोपाथ सती देहं त्यक्ष्यामीति त्वदुद्भवम् //
upasaṃhārakṛdrudras tenāmaṅgalabhāgayam cukopātha satī dehaṃ tyakṣyāmīti tvadudbhavam //
Rudra, the agent of dissolution, became enraged at that ill-omened turn of events. Then Satī—O you born of that line—declared, “I shall abandon this body.”
It uses the technical idea of upasaṃhāra (dissolution), characterizing Rudra as the force that brings endings—here expressed as divine wrath in a narrative setting rather than cosmic Pralaya itself.
Indirectly, it warns that actions deemed “amaṅgala” (inauspicious/ethically disruptive) can provoke grave consequences; a king or householder should uphold dharma to prevent social and ritual disorder.
No Vāstu or temple-rule detail appears in this verse; the ritual takeaway is the emphasis on auspiciousness (maṅgala) versus inauspiciousness (amaṅgala) in conduct and sacred events.
