Use it to help balance the flow of energy or qi in your home.
Tip No. 1: Energy flows through windows and doors, so pay attention to that. Arrange your bed or couch so that you can see it from the door but you're not facing it directly.
Tip No. 2: Don't sleep, sit on a sofa, or work at a desk with a window behind you. Contain your qi by having your back to a wall.
