Matsya Purana — Cosmography of Jambūdvīpa: Varṣas
माल्यवान्वै सहस्रैक आ नीलनिषधायतः द्वात्रिंशत्त्वेवमप्युक्तः पर्वतो गन्धमादनः //
mālyavānvai sahasraika ā nīlaniṣadhāyataḥ dvātriṃśattvevamapyuktaḥ parvato gandhamādanaḥ //
Mālyavān Mountain extends for a thousand (yojanas) up to the Nīla and Niṣadha ranges; likewise, Gandhamādana Mountain is also described as being thirty-two (yojanas in extent).
This verse is not about Pralaya; it belongs to the Matsya Purana’s cosmography (bhuvana-kośa), giving traditional measurements and placements of major mountains within the world-description.
Indirectly, such geographic catalogues support dharma through tīrtha-knowledge and the mapping of sacred regions; kings patronize pilgrimage routes and protect holy landscapes, while householders use such knowledge to orient vows, pilgrimages, and ritual travel.
No direct Vāstu or temple-rule is stated; the ritual relevance is contextual—these named mountains function as sacred reference points in Purāṇic spatial imagination used for pilgrimage narratives and locating holy realms.
