Matsya Purana — The Karmic Cause of Purūravas’ Beauty and Fortune
देवांस्त्रिभुवनश्रेष्ठान् गन्धर्वांश्च मनोरमान् उर्वशी संमता त्यक्त्वा सर्वभावेन तं नृपम् //
devāṃstribhuvanaśreṣṭhān gandharvāṃśca manoramān urvaśī saṃmatā tyaktvā sarvabhāvena taṃ nṛpam //
Urvashī—celebrated and admired—set aside even the gods, the finest in the three worlds, and the delightful Gandharvas, and with her whole heart chose that king alone.
Nothing directly—this verse is not about Pralaya; it highlights personal devotion/choice within a royal narrative rather than cosmic dissolution.
By portraying a king as worthy of wholehearted allegiance even above celestial allure, it implies the ideal of royal excellence—conduct, protection, and dignity that inspires loyalty and stabilizes household and kingdom.
None explicitly; the verse contains no Vastu Shastra, temple-building, or ritual procedure terminology—its focus is the king’s preeminence in a narrative setting.
