Matsya Purana — The Greatness of the Vibhūti-Dvādaśī Vow: Pushkara
स भवांल् लुब्धको जातः सपत्नीको नृपेश्वरः पुष्करप्रकरात्तस्मात् केशवस्य न पूजनात् //
sa bhavāṃl lubdhako jātaḥ sapatnīko nṛpeśvaraḥ puṣkaraprakarāttasmāt keśavasya na pūjanāt //
O lord of kings, because he did not worship Keśava, he fell away from the sacred precinct of Puṣkara and was born as a greedy hunter—together with his wife.
This verse does not address pralaya or cosmology; it teaches karmic consequence in a tīrtha context—neglect of Keśava’s worship leading to a degraded rebirth.
It frames worship of Vishnu (Keśava) as a core dharmic duty: even those of high status should maintain regular pūjā, especially when residing in or visiting sacred places like Puṣkara.
The key ritual point is pūjā of Keśava within a tīrtha’s ‘prākāra’ (sacred precinct); the verse implies that proper observance and reverence in such designated holy zones is mandatory for receiving tīrtha-phala.
