It is generally recommended that a Yantra be placed in the north/north-west direction facing the south/south-east direction in a room. However, this rule of thumb does not apply to the Vaastu Yantra as it is supposed to be placed in the south-west corner of the house, facing north-east. The Sri Yantra is supposed to be placed in the east, facing west. The Lord Kuber Yantra should be positioned in the north facing south or in the east facing west.
