Matsya Purana — Hiranyakashipu’s Boons
सिताभ्रघनसंकाशा प्लवन्तीव व्यदृश्यत रश्मिवती भास्वरा च दिव्यगन्धमनोरमा //
sitābhraghanasaṃkāśā plavantīva vyadṛśyata raśmivatī bhāsvarā ca divyagandhamanoramā //
She appeared like a dense mass of white clouds, as though floating; radiant with streaming rays, brilliantly luminous, and delightful with a divine fragrance.
It depicts a supernatural, luminous appearance—an omen-like theophany often used in the Pralaya narrative to signal divine intervention and protection amid cosmic dissolution.
Indirectly, it reinforces the Purāṇic ethic that when divine signs appear, a ruler (like Manu in the flood episode) should respond with reverence, discernment, and adherence to dharma rather than fear or impulsiveness.
While no explicit Vāstu rule is stated, the markers of divinity—radiance (tejas) and divine fragrance—are classic indicators used in ritual contexts to recognize auspicious presence, guiding proper reception (satkāra) and worship.
