Matsya Purana — Cosmography of Śākadvīpa and Successive Dvīpas: Mountains
शाको नाम महावृक्षः प्रजास्तस्य महानुगाः एतेषु देवगन्धर्वाः सिद्धाश्च सह चारणैः //
śāko nāma mahāvṛkṣaḥ prajāstasya mahānugāḥ eteṣu devagandharvāḥ siddhāśca saha cāraṇaiḥ //
There is a great tree known as Śāka, and numerous beings live there as its dependents and followers. Among them dwell the divine Gandharvas, the Siddhas, and also the Cāraṇas.
This verse does not directly describe Pralaya; it instead maps a cosmographic setting—an otherworldly great tree (Śāka) and the classes of celestial beings who inhabit that realm.
Indirectly, it supports the Matsya Purana’s broader aim of teaching right order (dharma) through cosmic hierarchy—showing that even higher realms have organized communities; kingship and household life are likewise expected to be orderly, duty-bound, and aligned with a larger sacred cosmos.
No explicit Vāstu or ritual procedure is stated here; the verse is primarily descriptive (cosmography). Its takeaway is contextual—Puranic texts often link sacred spaces and rituals to a layered cosmos populated by Gandharvas, Siddhas, and Cāraṇas.
