Lay the vāstu-puruṣa on your own home. Draw Varāhamihira’s maṇḍala over your plot, flat or floor plan; place the door, kitchen, shrine, beds, water and stairs; and see how each one reads in the Bṛhat Saṁhitā — then get a plain list of what to do, and a report to print.
One payment, as many homes, plots, flats and floors as you like. Everything runs in your browser — your plans stay on your device.
Vāstu begins with a simple picture: a being lies over every piece of ground, and forty-five gods hold him down, each in his own square — his pada. Where your door, hearth and bed fall among those squares is what the old texts read. The tool does that reading for you, carefully and with its sources shown.
A compass does not point to the north the texts mean. The tool gives the compass’s error at your place and date (from the IGRF-14 geomagnetic model, 1900–2030), the Sun’s rise and set, and Maya’s shadow-stick method — so the maṇḍala sits square to the real quarters.
Varāhamihira’s 81-pada grid (or his 64) drawn over your plot at its true angle, with all forty-five gods and the puruṣa’s limbs — and, on the 81, the six sūtras and nine atimarmas, the points not to press with pillars, pegs or pots. You can lay a picture of your floor plan underneath.
Drag the main door, shrine, kitchen, stores, water, bedrooms, toilets, stairs, pillars and trees onto the plan — or tap to place them. Where a verse speaks of it, each is read against that verse — the door against the 32 door results; toilets, stairs and tanks, which the texts don’t mention, against modern practice, labelled as such.
Maya’s āyādi — income, expense, yoni, nakṣatra, age and tithi from your length and breadth — with the nearest measure that passes if yours does not, and the usual tārā count from your birth star. Storey heights by Varāhamihira’s rule.
A short checklist of what a plan cannot show: the slope of the ground, the neighbours, the trees, what stands in front of the door, the soil test. Each question quotes the verse it comes from.
Every finding gathered into one list, worst first, with a concrete fix: move the door so far to the nearest good pada, turn the bed, shift the pillar off the marma. Save it all as a PDF, or keep a link to your plan.
Most of us do not live on a bare plot. Choose a single-storey house, a multi-storey house or building, a flat, or an office, and the tool adjusts its notes, its labels and the things you can place.
A 12 × 15 m plot facing nearly east, sixteen things placed on two floors — some well, some badly — so you can see how the readings work. The tool caught the well in the east, a pillar on the atimarma at the heart, a bed above the grain store and a toilet above the shrine, and said what to do about each.
The full example report — nine pages, exactly as the tool prints it: the two norths, the maṇḍala, every placement with its verse, the storeys and āyādi, the site checklist and the list of what to do.
Open the PDFMuch of what is sold as vāstu today is not in the old texts. Every reading in the tool carries a tag, so you always know whose word it is.
What Varāhamihira’s Bṛhat Saṁhitā (chapter 52; 53 in some editions) or Maya’s Mayamata actually says, with the verse number and the Sanskrit.
The common rules of modern vāstu — toilets, staircases, overhead tanks — that the texts do not state. Shown, but never mixed in with the text.
Where the tool has to interpret: an ambiguous verse, a layout the text only implies, a calculation it has to choose. Said plainly where it happens.
No. Everything is in plain English; the Sanskrit is there for anyone who wants to check it. The only astrological input is optional — your birth nakṣatra, for the tārā count that modern practice adds to Maya’s measures.
The width and depth of the plot or flat, which way the front faces, and roughly where the rooms are. A phone compass is fine for the facing, but check whether it shows magnetic or true north — many phones can show either (on an iPhone, Settings › Compass › Use True North) — and choose the same in the tool, which corrects a magnetic bearing for your place and date. A picture of the floor plan helps but is not needed.
Yes. Choose the kind of building and the tool adjusts its notes and the things you can place. For a flat the maṇḍala is drawn on the flat’s own walls; for several storeys you place rooms floor by floor, and the tool checks what sits above what and works out the storey heights by Varāhamihira’s rule.
No. The tool runs in your browser: your plan, a floor-plan picture you lay underneath and your answers stay on your device, and a link you copy to share a plan carries the plan inside the link itself. The one thing sent out is a place name you search for that is not in the built-in list of cities, which is looked up with the free Open-Meteo geocoder.
Yes. A larger screen makes placing rooms on the plan easier, and the PDF prints best from a computer.
Varāhamihira’s Bṛhat Saṁhitā, the chapter on vāstu (52 in the Sanskrit e-text, 53 in M. Ramakrishna Bhat’s translation), and Maya’s Mayamata (chapters 6 and 9, in T. Gaṇapati Śāstrī’s 1919 edition). Modern practice is included, but always labelled as such.
It is a careful reading of two classical texts applied to your plan. It does not judge structure, building codes, or your birth chart beyond the one measure of the āyādi. For a personal reading, book a session with Renay.
