Slavic ritual to cleanse a room of negativity

I received this ritual from the Slavic Magus (Rodnover) in Donbass in 2013. The ritual is performed in the Slavic (pagan) tradition. He works on personal Power with the support of the Ancestral system and native Gods.

You can use this ritual repeatedly, as soon as negativity has accumulated in a room (at home, office, etc.), an unpleasant person, your enemy, etc. has visited it. They can be used to clean the room if scandals have started in the house or after negative events (funerals, divorce, etc.), as well as if a lining has been discovered. In this case, the lining is eliminated, the room is washed with water and salt, and then this ritual is performed.
