If it cannot be moved
A staircase in the north loads the light direction with mass, which the tradition avoids. Where it is fixed, keep the space under it open rather than storing or building there, and keep the north wall of the house light in compensation.
What the উত্তর governs
North is Kubera’s direction, the one the tradition associates with wealth and with opportunity arriving. It is kept light and unobstructed: openings, windows and low, empty corners rather than heavy storage.
Where the সীঢ়ী belongs
A staircase is mass and movement together, which is why the tradition treats it like structure rather than circulation. It belongs in the heavy half, turns clockwise, and never sits over the centre of the plan.
