House Direction Astrology, also known as Vastu and home direction astrology, is an ancient practice that studies the impact of a house’s orientation on the lives of its residents. According to this science, the direction in which your home faces can influence health, wealth, relationships, and overall prosperity. Each direction—North, South, East, West, Northeast, Northwest, Southeast, and Southwest—carries specific energies that affect the flow of positive and negative vibrations in the house.
