Money, valuables, or a safe should be stored in a room on the north side of the house.
This is the side of Kubera, the god of wealth.
The door to this room should be facing north or east.
The walls should be painted yellow or mustard because these lead to an increase of wealth.
If the safe is large, it can be placed in the south, southwest, or west sides of the house, but it should always be set a few inches from the wall.
It should not be in the southwest or southeast corner, and should definitely not be in a northeast corner.
The safe should face north and open toward the north or east. It is inauspicious to have a safe opening to the south—this will cause a loss of money.
The safe should not be located under any beams.
Safes should be installed on a Monday, Wednesday, Thursday, or Friday, when the Sun is in the constellations of Dhanishtha, Rohini, Uttara, Swati, Shravan or Punarvasu.
