Matsya Purana — Yadu Lineage
निहता दानवाः सर्वे त्रैलोक्ये त्र्यम्बकेण तु असुराश्च पिशाचाश्च दानवाश्चान्धकाहवे //
nihatā dānavāḥ sarve trailokye tryambakeṇa tu asurāśca piśācāśca dānavāścāndhakāhave //
In the battle with Andhaka, Tryambaka (Śiva) struck down all the Dānavas across the three worlds—along with the Asuras and the Piśācas.
This verse is not about Pralaya; it emphasizes cosmic governance in the three worlds by showing Śiva (Tryambaka) eliminating disruptive beings during the Andhaka war.
Indirectly, it models dharmic protection: just as Tryambaka removes forces that threaten the worlds, a king is expected to restrain violence and disorder, and a householder to uphold social and ritual stability within their sphere.
No Vāstu or temple-building rule is stated here; the ritual takeaway is devotional—Tryambaka is portrayed as the protector who removes hostile forces, a theme often invoked in Śaiva worship and protective rites.
