Matsya Purana — Maya’s Nectar-Reservoir in Tripura and the Revival of the Slain in the Tripur...
द्वियोजनायतां दीर्घां पूर्णयोजनविस्तृताम् आरोहसंक्रमवतीं चित्ररूपां कथामिव //
dviyojanāyatāṃ dīrghāṃ pūrṇayojanavistṛtām ārohasaṃkramavatīṃ citrarūpāṃ kathāmiva //
(It was described as) two yojanas in length and a full yojana in breadth, furnished with ascents and connecting passages—variegated in form, like a wondrous tale.
This verse is not about Pralaya; it focuses on architectural description—specifically, the measured extent and internal connectivity (ascents and passages) of a planned settlement or fort.
For a king, it supports rajadharma through orderly urban planning—defensible dimensions, clear circulation routes, and well-designed approaches that aid administration, security, and public movement.
Architecturally, it specifies a canonical scale (2 yojanas by 1 yojana) and highlights functional design—āroha (approach/ramps) and saṅkrama (connections/crossings)—key Vastuvidya principles for access and circulation.
