Sthāpatya Veda & Vāstu Compendium

Vāstu & Sthāpatya Veda Compendium

The rigorous architectural, mathematical, and biophysical documentation for Vāstu Śāstra. From Sanskrit verse recensions to computational Shoelace polygon centroids, 16-zone angular slicing, and National Building Code of India (NBC 2016) statutory compliance.

Mānasāra VāstuśāstraCh. 3 (Vāstuvidhāna), v. 1–2
B · Classical commentary

वास्तु यस्माद् निवासाय कल्पितं सर्वदेहिनाम्। तस्माद् वास्तु इति प्रोक्तं तज्ज्ञानेन विधीयते॥

vāstu yasmād nivāsāya kalpitaṃ sarvadehinām | tasmād vāstu iti proktaṃ tajjñānena vidhīyate ||

Translation:Because it is conceived as the sacred abode for all living beings, it is called Vāstu. True architecture is that which is systematically executed in alignment with this divine science.

Illustration, not the engine

Change a dimension and watch the modular arithmetic move. The residues here are computed in the page so the steps are visible; the authoritative values come from the Vaasthu engine.

Perimeter = 2 × (L + W) ÷ 1.5 ft/hasta = 93 hasta

Āya (×8 mod 12)

Vāra (×9 mod 7)
Budha (Mercury)
Nakṣatra (×8 mod 27)

Āya clears Vyaya — the condition the set is checked for.

Yoni 7 (North) is an odd, favourable yoni — Exalted / abundance.
