1.Make sure that the direction of the unmarried girl's room is in the north-west direction of the house. It should never be in the south-west direction as that delays matrimonial opportunities.
2. Paint the walls of the house in pastel shades as this invites positive energy. Stay away from black or brown paints or wallpapers. 
3. Keep the door of the bathroom closed when not in use, especially the one attached to the girl's room. 
4. A marriageable boy must avoid sleeping in South-East bedroom.
5. Girl (after her menstruation cycle has started) must avoid sleeping in North-East and South-West bedroom.
6. Keep mirrors only inside the rooms and not outside. They can be placed in the west and south walls but should not be facing the bed. 
7. Below the bed, the area should be empty and clean. Find another spot if you have kept some belongings there as that brings bad luck or delays the prospect of marriage.
