Matsya Purana — Brahmā’s Four Faces
केचित् प्रधानम् इत्य् आहुर् अव्यक्तम् अपरे जगुः एतद् एव प्रजासृष्टिं करोति विकरोति च //
kecit pradhānam ity āhur avyaktam apare jaguḥ etad eva prajāsṛṣṭiṃ karoti vikaroti ca //
Some call it Pradhāna, the primordial principle; others declare it to be Avyakta, the Unmanifest. It alone brings forth the creation of beings, and it also transforms the created world.
It identifies the unmanifest material principle (Pradhāna/Avyakta) as the underlying cause that generates beings and also brings about their change—implying cyclical manifestation and reconfiguration across cosmic phases, including dissolution and re-creation.
By grounding the world in an impersonal, law-governed causal principle, it supports the Purāṇic ethic that rulers and householders should act in harmony with cosmic order (dharma), recognizing that prosperity, decline, and social change are part of a larger, regulated process.
No direct Vāstu or ritual rule is stated; however, the verse supplies the cosmological premise often used in ritual and temple thought: visible forms arise from an unmanifest source, so consecration and design symbolically “manifest” order from the unseen principle.
