Matsya Purana — Cosmography of Śākadvīpa and Successive Dvīpas: Mountains
अन्धकारकदेशात्तु मुनिदेशस्तथा परः मुनिदेशात्परे चापि प्रोच्यते दुन्दुभिस्वनः //
andhakārakadeśāttu munideśastathā paraḥ munideśātpare cāpi procyate dundubhisvanaḥ //
Beyond the region called Andhakāraka lies the tract known as Munideśa; and beyond Munideśa again is declared the region called Dundubhisvana—“the reverberation of the drum.”
This verse is not about Pralaya; it is a Vastu-style classification of named regions/zones, mapping successive areas beyond one another.
It supports the king’s/householder’s duty to found settlements and build correctly by recognizing prescribed zones—useful for planning towns, temples, and precincts according to traditional spatial categories.
It enumerates successive Vastu-geographic zones, including a region characterized by ‘drum-like reverberation’ (Dundubhisvana), implying attention to site-omen qualities (especially sound) when defining precincts.
