Best placed in the South-West
The south-west is the master bedroom’s own corner: the heaviest, most grounded part of the plan, for the people who carry the household. The tradition adds that the bed should sit in the room’s south-west too, with the head to the south or west.
What the South-West governs
The south-west — Nairutya — is the earth corner: the heaviest, most grounded part of the plan. It is where the tradition puts what should not move, which is why the master bedroom and the structural mass belong here and water does not.
Where the Master bedroom belongs
The master bedroom is meant to sit in the heaviest, most settled part of the house, on the theory that the person carrying the household should sleep where the building is most grounded. It is a placement about stability rather than energy.
