Matsya Purana — The Array of the Gods: Description of the Vaiṣṇava Host and the Lokapālas
आदित्या वसवो रुद्रा अश्विनौ च महाबलौ सबलाः सानुगाश्चैव संनह्यन्त यथाक्रमम् //
ādityā vasavo rudrā aśvinau ca mahābalau sabalāḥ sānugāścaiva saṃnahyanta yathākramam //
The Ādityas, the Vasus, the Rudras, and the two mighty Aśvins—together with their forces and attendants—arrayed themselves in readiness, each in due order.
It does not describe Pralaya directly; it highlights cosmic administration—standard Deva classes (Ādityas, Vasus, Rudras, Aśvins) acting in ordered coordination, a theme often contrasted with disorder during dissolution.
The emphasis on yathākramam (proper order) models dharmic governance: a king or householder should organize people, resources, and responsibilities systematically, with clear ranks and preparedness in times of threat.
While not architectural, the key idea is ordered arrangement (krama), which parallels Vastu and ritual procedure: correct sequencing and placement of participants/forces is treated as a principle of efficacy and auspiciousness.
