Commentary and interpretation by Bangalore Niranjan Babu
House Architecture (Śālā Houses)
King Bhoja details four basic models of residential houses built around courtyards, known as Śālās:
- Ekaśālā
- A single-block house — the text describes 15 distinct types of Ekaśālā configurations.
- Dviśālā
- A two-wing residence arranged around a partial courtyard.
- Triśālā
- A three-wing configuration enclosing the courtyard on three sides.
- Catuśśālā
- A fully enclosed quadrangle — the most complete residential form, with further combinations extending to the Daśaśālā (ten-wing complex).
These courtyard models remain directly applicable to contemporary residential design, as explored in the Private Residence article.
Doors and Entrances
The text is highly specific about door placements. It strictly warns against having a door in the exact middle of a house, stating that such placement indicates negative effects and "ruin of the family". Instead, it recommends placing doors in exalted zones:
- Mahendra (Indra)
- Bṛhatkṣata
- Kusumadanta
- Bhallāṭa
The text also advises that a door should not have more than five frames (śākhās) — a guideline consistent with the Mayamata's treatment of entrance design.
Foundations and Energy Lines
The Samarāṅgaṇa Sūtradhāra emphasises the critical importance of proper foundations (bhūmilamba) for structural stability. When discussing the metaphysical grid of the Vāstu Puruṣa, the text identifies specific energy lines and vulnerable points:
- Śiras
- The head point — the most sensitive zone at the north-east.
- Vaṃśa
- The spine line running north to south.
- Sandhi and Anusandhi
- Junction points where energy lines intersect.
- Marma
- Vital vulnerability points that must never bear structural loads.
- Mahāvaṃśa
- The great central axis — the most powerful energy line in the grid.
Town Planning and Security
Town Layouts
The text provides extensive guidelines on village and town planning. In its model town, it recommends laying out exactly 34 streets running from east to west and north to south, specifically aligned on the Vaṃśas (energy lines). This systematic approach to urban design is applied in modern practice through the commercial Vāstu framework.
Landscaping
The text highlights the ecological and aesthetic importance of gardens, recommending that a beautiful belt of trees and plants surround the entire town — a principle that modern campus design would recognise as landscape buffering.
Fortifications
To ensure security, the Samarāṅgaṇa Sūtradhāra describes two types of fortifications:
- Natural: Utilising water, mud, forests, deserts, mountains, or caves as defensive barriers
- Artificial: Creating parapets, ramparts, and deep moats around the settlement
