Matsya Purana — Design and Splendour of Tripura: Maya’s Threefold Moving Fortress
दिव्यभोगोपभोगानि नानारत्नयुतानि च पुष्पोत्करैश्च सुभगास् त्रिपुरस्योपनिर्गमाः परिखाशतगम्भीराः कृता मायानिवारणैः //
divyabhogopabhogāni nānāratnayutāni ca puṣpotkaraiśca subhagās tripurasyopanirgamāḥ parikhāśatagambhīrāḥ kṛtā māyānivāraṇaiḥ //
Tripurā’s exits and gateways were splendid—furnished with celestial luxuries and enjoyments, adorned with many kinds of jewels, and beautified with heaps of flowers. Around it were moats, hundreds of them, exceedingly deep, constructed as barriers to ward off deceptive māyā and hostile stratagems.
This verse is not about Pralaya; it describes engineered splendor and defensive planning—Tripura’s jewel-adorned gateways and deep moats designed to counter hostile deception.
It reflects a king’s rajadharma of protection: establishing secure, well-designed city defenses (gateways, moats, and anti-stratagem measures) while maintaining prosperity and public auspiciousness.
Architecturally, it highlights Vastuvidya themes—ornamented gateways/approaches and deep moats as layered defenses, explicitly including measures against “māyā” (deceptive tactics), a hallmark of strategic fortification planning.
