Matsya Purana — Catalogue of the Eighteen Puranas
पुरातनस्य कल्पस्य पुराणानि विदुर्बुधाः धन्यं यशस्यमायुष्यं पुराणानामनुक्रमम् यः पठेच्छृणुयाद्वापि स याति परमां गतिम् //
purātanasya kalpasya purāṇāni vidurbudhāḥ dhanyaṃ yaśasyamāyuṣyaṃ purāṇānāmanukramam yaḥ paṭhecchṛṇuyādvāpi sa yāti paramāṃ gatim //
The wise know the Purāṇas to belong to the ancient kalpa. The ordered synopsis (anukrama) of the Purāṇas is auspicious, fame-giving, and life-enhancing; whoever recites it or even listens to it attains the supreme state.
Indirectly, it situates Purāṇic knowledge within an ancient kalpa (cosmic era), implying that Purāṇas preserve primordial accounts of cosmic cycles (including creation and dissolution), though this verse itself focuses on the merit of their ordered synopsis.
It recommends dharmic practice through pāṭha (recitation) and śravaṇa (listening). For householders and rulers alike, supporting and participating in Purāṇic teaching is presented as a meritorious discipline that brings auspiciousness, reputation, and well-being.
No specific Vāstu or temple rule is stated; the ritual takeaway is the phala-śruti: even hearing or reciting the Purāṇa-anukrama is itself a sanctifying act leading toward the highest spiritual attainment.
