The symbols from this book can be applied in any premises. It can be private houses and cottages, or it can be apartments in high-rise buildings. They can also be used in offices, warehouses, industrial and municipal buildings. If you use these symbols in apartment buildings, there is, of course, a chance that ghosts from other apartments can immediately fly in your just cleansed area. But if you use the symbols from this book correctly, such uncontrolled things will not happen, because in the fourth part of the book I give symbols to protect the apartment and house. Protective symbols create a space around your apartment or house where ghosts can no longer get in.
