Keep the windows clean at all times and the curtains pulled back during the daytime, to allow maximum light to enter. But make sure you don’t have any windows un-curtained at night Curtains should not just hang down limply on either side of a window. They should be tied back on either side so that they hang in graceful folds.

The ratio of windows to doors in any room should not exceed 3:1.

Ideally, windows should open outwards. Arched windows and octagonal windows are better. If windows open inwards, place a plant on the windowsill or hang a wind-chime, to deflect the negative energies.
