Matsya Purana — Design and Splendour of Tripura: Maya’s Threefold Moving Fortress
आरामैश्च विहारैश्च तडागवटचत्वरैः सरोभिश्च सरिद्भिश्च वनैश्चोपवनैरपि //
ārāmaiśca vihāraiśca taḍāgavaṭacatvaraiḥ sarobhiśca saridbhiśca vanaiścopavanairapi //
“(A settlement/region) should be graced with pleasure‑gardens and recreation grounds, with tanks, banyan trees, and public squares; with lakes and rivers; and also with forests and cultivated groves.”
This verse is not about Pralaya; it focuses on sustaining orderly human life through well-planned landscapes—water sources, parks, and public spaces.
It reflects a king’s duty of loka-saṅgraha (public welfare): creating tanks, maintaining riversides, and providing gardens and squares that support health, economy, and civic life.
Architecturally, it is a Vastu-oriented checklist for settlement planning: integrate waterworks (taḍāga, saras, sarit), shaded nodes (vaṭa), and communal spaces (catvara) along with groves and forests.
