वास्तु-पुरुष-मण्डलम् · classical architectural grid

The vāstu maṇḍala

The 81-pada Paramaśāyika grid, its 45 vāstu-devatās, the eight direction-deities, and the classical plot rules — cited from Mayamatam, Mānasāra, and Bṛhat-Saṃhitā Ch. 52–56. The geometry is exact; the auspice-grades are tradition.

Vāstu is a classical architectural tradition, not a science-claim. Grid geometry and citations are exact; classifications are cultural record — no fear, no remedies, no predictions.
