Several years before I began occult practice I used to watch certain TV shows that addressed esoteric topics, featuring various guests.
One such guest spoke of a magician being able to change the energies of a place. In his example, a magician moved into a condo where junkies used to hang every evening inside the ground floor hallway and basically do their shit, creating all sorts of unpleasantness for the people living there. Some time after the magician moved in, the junkies were gone. The newer energies of the place, having been set into motion by the magician, manifested in ways that kicked the junkies out for good. Those ways can consist of police raids, tenants uniting to throw out the trash, etc.
These things can be done for good, such as presented in the script for my
ritual for a home. They can also be done on a regular basis, through periodic rituals targeting a certain building or area. The latter will wear off after some time unless the rituals are anchored into talismans that have to be placed inside the targeted zone, but even so, the talismans are susceptible to being found and destroyed or discarded. The former will be longlasting, even without being anchored into a talisman, at least until such time the magician decides to change the energies again.
