Concept: Ritual order (niyama) expressed as spatial order—measures that preserve śauca and durability.
Application: Implement prescribed tapering and channel sizing to prevent pooling and to maintain the sanctity and longevity of the structure.

FAQs
Vāstu-vidyā: it gives proportional rules for a layout—front breadth equals the base-width, the rear is half, and the drainage/water-course (toya-mārga) is set at one-third of the main breadth.
Alongside theology, the Agni Purana preserves applied sciences like Vāstu—precise construction ratios and infrastructure planning (notably drainage), showing its wide, practical scope.
In Purāṇic Vāstu, correct proportioning and proper water-drainage are treated as dharmic building practice—supporting cleanliness, stability, and auspiciousness of the dwelling or sacred structure.
