Best placed in the পূর্ব
An east-facing door takes the first sun and is the placement most associated with reputation and steady dealings. It suits households whose day starts early.
What the পূর্ব governs
East is Indra’s direction and the Sun’s: the first light, and the direction the tradition orients study, prayer and the start of the day towards. Like the north it wants openness rather than mass.
Where the মুখ্য দ্বার 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.
