A cleared space is a place for mental clarity, creativity, and vitality. People come and go and everyone leaves a small residue of their energy. Everyone's energy holds old and new thoughts, blockages, patterns, lots of clutter. It is common our own energy field picks on these carrying them everywhere we go. They get mixed with our own thoughts, and patterns - creating a salad of energy and emotions that we can't even describe where they are coming from. Aka - "I feel weird today". This is why we cleanse, to remove everything that is not ours, or no longer serving its purpose for being with us, to remove all the layers and junk we have naturally picked up and can't see. To reset - - refresh and be able to be our true self, and radiant self.
