Matsya Purana — The Karmic Cause of Purūravas’ Beauty and Fortune
रूपकामः स मद्रेशस् तपसे कृतनिश्चयः राज्यं मन्त्रिगतं कृत्वा जगाम हिमपर्वतम् //
rūpakāmaḥ sa madreśas tapase kṛtaniścayaḥ rājyaṃ mantrigataṃ kṛtvā jagāma himaparvatam //
That ruler of Madra, longing for beauty, resolved to undertake austerities (tapas); entrusting the kingdom to his ministers, he departed for the Himālaya mountains.
This verse does not address pralaya or cosmology; it focuses on a royal episode where a king chooses tapas, illustrating personal transformation rather than cosmic dissolution.
It highlights responsible renunciation: even when pursuing ascetic goals, the king secures continuity of governance by placing the kingdom under ministerial administration—an ideal of orderly rule and duty before withdrawal.
No Vāstu, temple-building, or ritual procedure is specified; the key takeaway is the ascetic setting of the Himālaya, a traditional locus for tapas in Purāṇic practice.
