Matsya Purana — Conclusion of the Prayaga Mahatmya: Kingship Restored
प्रयागं स्मर वै नित्यं सहास्माभिर्युधिष्ठिर स्वयं प्राप्स्यसि राजेन्द्र स्वर्गलोकं न संशयः //
prayāgaṃ smara vai nityaṃ sahāsmābhiryudhiṣṭhira svayaṃ prāpsyasi rājendra svargalokaṃ na saṃśayaḥ //
Remember Prayāga indeed every day, O Yudhiṣṭhira, together with us; O best of kings, you yourself will attain the world of heaven—there is no doubt.
This verse does not discuss pralaya; it teaches tīrtha-māhātmya—daily remembrance of the sacred place Prayāga as a means to gain heavenly merit.
It frames a practical dharma for rulers and householders: maintain daily sacred recollection (smaraṇa) of a tīrtha like Prayāga, cultivating virtue and accruing puṇya that leads to higher worlds.
No Vāstu or temple-building rule is stated; the implied ritual takeaway is smaraṇa (devotional recollection) of Prayāga as a simple, repeatable daily practice linked to spiritual reward.
