Best placed in the East
East is the accepted alternative to the north-east and shares its logic: first light, and the deity facing west while the worshipper faces east.
What the East 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 Pooja room belongs
The pooja room belongs to the light half of the plan. The tradition puts it where the first sun falls and keeps it away from anything heavy, wet or waste-carrying — including sharing a wall with a bathroom, which matters more than the compass point.
