Matsya Purana — Lineage of the Pitṛs
प्राह देवी यदारब्धं तत्कार्यं मे न संशयः किंत्ववश्यं त्वया मर्त्ये हतयज्ञेन शूलिना //
prāha devī yadārabdhaṃ tatkāryaṃ me na saṃśayaḥ kiṃtvavaśyaṃ tvayā martye hatayajñena śūlinā //
The Goddess said: “Whatever has been undertaken must indeed be brought to completion—of this I have no doubt. Yet it is inevitable that, in the mortal realm, you—Śūlin, the trident-bearer—will become the slayer of the sacrifice (yajña).”
It does not describe cosmic pralaya; it portrays a ritual “dissolution” where a sacrifice (yajña) is fated to be destroyed, emphasizing moral causality rather than cosmic flood or dissolution.
It implies that undertakings—especially rites—must align with dharma; otherwise, even a formally arranged yajña can be overturned. For householders and rulers, it warns against pride, exclusion, or adharma in public rituals.
The ritual significance is central: the verse frames the yajña as an act that can be “killed” when corrupted, highlighting that correct intention, legitimacy, and adherence to sacred order are as crucial as the external procedure.
