Matsya Purana — Yadu Lineage
हता देवमनुष्ये स्वे पितृभिश्चैव सर्वशः संपृक्तो दानवैर्वृत्रो घोरो हालाहले हतः //
hatā devamanuṣye sve pitṛbhiścaiva sarvaśaḥ saṃpṛkto dānavairvṛtro ghoro hālāhale hataḥ //
In that calamity, gods and humans alike were slain, and even the Pitṛs (ancestral spirits) were struck down on every side. The dreadful Vṛtra too—mingled with the Dānavas—was destroyed in the Hālāhala poison.
It depicts a dissolution-like catastrophe where even higher classes of beings (Devas and Pitṛs) perish, using the Hālāhala poison as a symbol of cosmic-level destructive force.
Indirectly, it underscores the Purāṇic ethic of humility and vigilance: worldly power and lineage are fragile, so rulers and householders should prioritize dharma, protection of dependents, and merit-making acts (dāna, yajña) over arrogance.
No direct Vāstu or temple-rule instruction appears in this verse; its ritual takeaway is the Purāṇic emphasis on safeguarding life and purity against ‘poison’ (viṣa) motifs—often addressed through śānti rites and protective observances in broader tradition.
