Vastu

Sleep direction

Vastu says head to the south and gives the same answer to everybody. Ba Zhai says it depends on the year you were born. Both are here, side by side, and the rows where they disagree are marked rather than reconciled.

Birth details

The time matters more than anything else here. Two hours out and the ascendant moves a whole sign, which rearranges every house in the chart.

Gender (optional)

Two readings are defined in terms of it — the Kua number in vastu and the luck pillars in the Chinese chart — and neither has a formula for anything beyond male and female. Answer “other” or leave it and those two say so instead of guessing. Nothing else in your chart uses it.

The vastu column does not depend on any of this — it is the same for everyone and would be identical if you typed in somebody else’s birthday. Only the Ba Zhai column is personal, and only that column needs the gender question. Leave it and you get the vastu reading in full.

Why anyone cares about this one

Of everything in vastu, the direction of the bed is the rule most people have already heard, and usually in the form of a prohibition: never sleep with your head to the north. It is also the easiest rule in the whole subject to act on. Turning a bed costs an afternoon, where moving a kitchen does not.

Two traditions, two premises

The vastu answer is impersonal. It is derived from the orientation of the body against the earth, it is the same for a newborn and for somebody of eighty, and nothing you could tell this page would change it.

The Ba Zhai answer is the opposite: it is derived entirely from you, and two people sharing a bed can have directly opposed best answers. When that happens the tradition has its own conventions for whose direction wins, and this page does not pretend to settle it.

Where the two point the same way, that is worth knowing. Where they do not, that is worth knowing too, and it is marked as a disagreement rather than resolved into a single verdict that neither tradition would recognise.

What this is not

A medical claim. The environmental readings behind some vastu rules are reasonable on their own terms — light, heat, prevailing wind — but nothing here is a statement about sleep quality, circulation, or health, and if you are sleeping badly the direction of the bed is not the first thing to investigate. The method page sets out where the line is.
