Best placed in the ಉತ್ತರ
A north-facing door is among the most sought placements, read as opening the house to Kubera’s direction and to opportunity that arrives without being chased.
What the ಉತ್ತರ 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 ಮುಖ್ಯ ದ್ವಾರ belongs
The main door is where the tradition says the house meets the world, and it is the placement most people can still change — a door can be re-hung where a kitchen cannot be moved. The light directions take it; the heavy ones are held to admit what you would rather keep out.
