Matsya Purana — Paurava Genealogy
अत्रानुवंशश्लोको ऽयं गीतो विप्रैः पुरातनैः ब्रह्मक्षत्रस्य यो योनिर् वंशो देवर्षिसत्कृतः क्षेमकं प्राप्य राजानं संस्थास्यति कलौ युगे //
atrānuvaṃśaśloko 'yaṃ gīto vipraiḥ purātanaiḥ brahmakṣatrasya yo yonir vaṃśo devarṣisatkṛtaḥ kṣemakaṃ prāpya rājānaṃ saṃsthāsyati kalau yuge //
Here is this genealogical verse, sung by the ancient sages: that revered lineage—its source being the Brahma-Kṣatra (the Brahmin–Kshatriya stock), honored by divine seers—will, upon reaching King Kṣemaka, come to an end in the Kali age.
This verse is not about cosmic dissolution (pralaya); it speaks of a historical-dynastic “ending” (saṃsthā) of a royal lineage in the Kali Yuga, culminating with King Kṣemaka.
Indirectly, it frames kingship within impermanence: even revered, seer-honored dynasties end in time. In the Matsya Purana’s ethical outlook, this supports dharmic governance and legacy—rule righteously, since worldly sovereignty is finite.
No Vāstu, temple-building, or ritual procedure is mentioned in this verse; its focus is lineage documentation and Puranic chronology (especially the Kali Yuga endpoint of a dynasty).
