Matsya Purana — Vishnu’s Names Across Yugas and the Gods’ Refuge During the Tārakāmaya War
तान्घनौघान्स तिमिरान् दोर्भ्यामाक्षिप्य स प्रभुः वपुः संदर्शयामास दिव्यं कृष्णवपुर्हरिः //
tānghanaughānsa timirān dorbhyāmākṣipya sa prabhuḥ vapuḥ saṃdarśayāmāsa divyaṃ kṛṣṇavapurhariḥ //
Casting aside those dense masses of darkness with His two arms, that Lord—Hari, of dark-hued body—then revealed His radiant, divine form.
It presents a Pralaya-style motif where oppressive darkness (tamas) is removed by the Lord, signaling restoration of cosmic order and the reappearance of divine light/vision.
By analogy, it frames dharma as the act of removing “darkness” (confusion, injustice, fear) and making what is divine/true visible—an ideal for rulers and householders who must protect, clarify, and uphold order.
No direct Vāstu or ritual procedure is stated; indirectly, it supports the ritual-visual principle of darśana—creating conditions (light, clarity, unobstructed sight) for beholding the deity in worship and temple settings.
