Matsya Purana — Yadu Lineage
यापयामः कृच्छ्रमिदं यावदभ्येति नो गुरुः निवृत्ते च तथा शुक्रे योत्स्यामो दंशितायुधाः //
yāpayāmaḥ kṛcchramidaṃ yāvadabhyeti no guruḥ nivṛtte ca tathā śukre yotsyāmo daṃśitāyudhāḥ //
“Let us endure this hardship until our teacher comes back. And when Śukra too has withdrawn, then we shall fight—armed and fully prepared.”
This verse does not address Pralaya directly; it focuses on enduring hardship and choosing the proper moment for battle under the guidance of a guru.
It reflects Kshatriya/royal ethics: patience under adversity, deference to the preceptor’s counsel, and engaging in conflict only when conditions are appropriate—while remaining prepared and disciplined.
No Vastu or temple-ritual rule is stated here; the key takeaway is strategic restraint and guru-guided readiness (daṃśitāyudha) rather than architectural procedure.
