Matsya Purana — Tārakāsura’s Austerity and Boon; Mobilization for War; Bṛhaspati’s Fourfold P...
यमं सेनापतिं कृत्वा शीघ्रमेवं दिवौकसः इत्युक्ताः समनह्यन्त देवानां ये प्रधानतः //
yamaṃ senāpatiṃ kṛtvā śīghramevaṃ divaukasaḥ ityuktāḥ samanahyanta devānāṃ ye pradhānataḥ //
Having swiftly appointed Yama as their commander-in-chief, the gods—those foremost among the Devas—upon being so addressed, immediately armed themselves and made ready.
This verse does not discuss Pralaya; it depicts a wartime mobilization where the Devas appoint Yama as commander and prepare for conflict, emphasizing cosmic order defended through organized action.
It models rajadharma in principle: appoint a qualified commander, act swiftly in crisis, and ensure preparedness—leadership through delegation and disciplined readiness to protect order (dharma).
No Vastu or ritual procedure is specified here; the takeaway is strategic readiness rather than temple architecture or ceremonial rules.
