The square (and rectangle) is Vāstu's preferred structural form

Prāṇa relevance

The square's Earth-resonance gives stability of prāṇa flow: 'Geometrical regularity in design promotes regularity of prāṇa flow.' Curved/irregular geometries produce 'persistent inconsistency in the circulation of prāṇa'. The form-choice is thus a prāṇa-circulation choice, mediated by the elements (Earth=square=stable prāṇa; Air/Water=circle=mobile prāṇa). Interpretive at the form↔prāṇa joint but stated.

Statement
Square — and equivalently rectangle, since every rectangle partitions into squares — is Vāstu's preferred form for structural foundations, by virtue of the square's inherent stability and its resonance with the Earth element (the most stable of the Five Elements). Circles, ellipses, triangles and many-sided polygons are dispreferred for permanent residence: the circle's perpetual motion suits only the eternal migrant (yurt, geodesic dome); the ellipse (twin foci) is worse; the triangle (Fire's silhouette) is energetically unstable and too 'acute'; octagons/hexagons are used only occasionally, mainly for sacred structures. Asymmetrical areas must be 'squared'. Preferred rectangle ratios (per Śilparatna) are 1:2, 2:3, 3:5 (Fibonacci, →~1:1.6); guṇāmśa permits 4:5…4:28 EXCEPT the padona (quarter- short) ratios 4:7, 4:11, 4:15, 4:19, 4:23, 4:27; ratios beyond ~1:7 enclose too little area to be practical.

Conditions
permanent residence / secular buildings (the migrant/sacred exceptions noted); rectangles ≡ squares for Vāstu purposes
Exceptions
yurts/domes for nomads & retreat centres (circle); pyramids of four truncated triangles are acceptable IF they have a clear Brahma Sthāna whose perimeter the flattened top matches; 16/32-sided polygons occasionally for sacred structures; padona ratios forbidden (reason 'unknown', linked to the quarter-short = inauspicious tradition)
