The Head of Vaastu-Purush lies in the North-East (Eashan) Direction and is occupied by Mercury (Buddha) and Ruled by Lord Shiva. Accordingly, the place of conducting mental work and the worship chamber in a house is to be situated in that direction.
The head should be secure. Therefore, the North-East is should be kept free from heavy structures like pillars, etc.
While constructing one should therefore take care that there is enough ventilation in the North-East direction of the building. Toilet should never be constructed on the North-East. Yes, only a Bathing room can be constructed.
Keep the North-East corner of the Building always clean and pure. Always light incense sticks here as North-East is the best place for worship place.
