Start at the front door of the home and light your smudge stick. Then, begin to move around the home. Move mindfully and with care, walking clockwise around the entire perimeter of the home. Be sure to allow the smoke to drift into even the hidden spaces, like inside closets, basements and dark corners. If there are stairs, just go up or down when you encounter them. Then keep moving clockwise until you meet the stairs again. Then continue to go down or up the stairs and resume the main floor.
