Matsya Purana — The Rite and Glory of Meru-Dāna: The Tenfold ‘Gift of Meru’ and Mountain-Offe...
एवमभ्यर्च्य तं मेरुं मन्दरं चाभिपूजयेत् यस्माच्चैत्ररथेन त्वं भद्राश्वेन च वर्षतः //
evamabhyarcya taṃ meruṃ mandaraṃ cābhipūjayet yasmāccaitrarathena tvaṃ bhadrāśvena ca varṣataḥ //
Thus, having duly worshipped Mount Meru, one should also offer reverent worship to Mount Mandara—because you are associated with the Varṣa regions called Caitraratha and Bhadrāśva.
This verse is not about Pralaya; it belongs to the Matsya Purana’s cosmological mapping of the world, linking ritual worship to cosmic landmarks (Meru, Mandara) and the Varṣa divisions (Caitraratha, Bhadrāśva).
It frames a dharmic practice of honoring sacred geography: a king or householder is encouraged to perform orderly worship (abhyarcya, abhipūjayet) that aligns human ritual with the Purāṇic cosmic order and its named regions.
The ritual significance is explicit: after worshipping Meru, one should also venerate Mandara, indicating a prescribed sequence of worship tied to Purāṇic cosmography—useful for designing pilgrimage recitations, temple readings, and ritual manuals that follow Matsya Purana’s geographic theology.
