What Vāstu Śāstra actually is
Vāstu means a site or dwelling place; śāstra means a systematic treatise. Taken together the term names the branch of the Indian technical literature that deals with building: selecting and testing ground, orienting a structure to the directions, setting out a plan on a measured grid, fixing proportion, and timing the ritual stages of construction.
It belongs to the wider śilpa-śāstra tradition — the literature of craft and making — and sits alongside iconography, sculpture and image-measurement rather than apart from them. In its own texts it is a builder’s discipline. Proportion, module and measurement occupy far more of the page than prescription about where to sleep.
The source texts
The tradition is not a single book. These are the principal surviving works that later writers treat as authoritative:
- Bṛhat Saṃhitā — Varāhamihira, c. 6th century CE. An encyclopaedic work whose chapters on architecture cover site examination, the testing of soil, house types, proportion and the timing of building. It is the earliest of these that can be dated with reasonable confidence, and it also happens to be a standard Jyotisha source, which is one reason the two subjects are often discussed together.
- Mayamata — a South Indian treatise of the śilpa tradition, dealing with village and town layout, ground selection, measurement, houses, temples and images.
- Mānasāra — the other major South Indian manual, similar in scope and often studied alongside the Mayamata.
- Samarāṅgaṇa Sūtradhāra — attributed to the Paramāra king Bhoja, 11th century, covering town planning, residential and temple architecture, and iconography.
- Viśvakarma Prakāśa — a later compendium of the same material, widely quoted in North Indian practice.
These works disagree with one another on plenty of detail, in the ordinary way of a long technical literature. Where a modern source presents a Vastu rule as unanimous, it is usually worth asking which text it comes from.
The three ideas everything else is built on
Whatever the treatise, three organising ideas recur.
1. The vāstu-puruṣa-maṇḍala
A square grid, most often 8×8 or 9×9 cells, laid over the site. A figure — the vāstu-puruṣa — is conceived as lying across it, and a set of presiding deities is assigned to the cells, with Brahmā at the centre. The maṇḍala is the layout instrument: it fixes the centre, sets the module from which every other measurement derives, and tells the builder which parts of the plan are structurally and ritually weighted. It is best understood as a proportioning device carrying a cosmological reading, rather than as a chart of lucky and unlucky corners.
2. Orientation
Buildings are set to the cardinal directions, and the four intercardinal directions are named and treated as meaningful in their own right. Orientation in the texts is determined by observation — classically by a gnomon and the shadow it casts — not by a compass, and the concern is as much practical (sun, prevailing wind, drainage, the run of the ground) as symbolic.
3. The five elements
The pañca-mahābhūta — earth, water, fire, air and space — supply the descriptive vocabulary through which sites and parts of a building are characterised. This is the framework that most modern popular Vastu foregrounds, and it is the one most loosely handled.
Classical Vastu and modern Vastu are not the same thing
This is the single most useful thing to know about the subject. The classical treatises are overwhelmingly concerned with temples, civic layout, proportion, module and the ritual sequence of construction. The Vastu that circulates today — room-by-room prescriptions for an apartment, corrective objects, direction-specific remedies — is a twentieth-century domestic adaptation, assembled from fragments of that literature and considerably expanded.
That does not make the modern material worthless, and plenty of it restates sensible building practice for a hot climate. But it does mean two claims should be kept apart: what the source texts say, and what contemporary practice recommends. A page that presents the second as the first is misrepresenting the tradition, and the confident, remedy-selling register that much Vastu writing adopts is not a register the classical texts themselves use.
AdiVeda’s editorial position on Vastu is the same as on the astrological classifications: describe the tradition accurately, name the source, mark what is late or disputed, and do not manufacture certainty the literature does not contain.
What AdiVeda publishes on Vastu today
Honestly: this page. Vastu is a new subject area here, and no dedicated Vastu guides have been published yet — there is no article series, no calculator, and no Vastu consultation offered. This hub exists as the entry point so that material can be added to a proper home rather than scattered, and so that readers are not sent to a page that promises more than the site currently holds.
If and when Vastu articles are published, they will appear here. Nothing on this page should be read as a Vastu assessment of a specific building.
