Lets see… I do white light visualizations, sage regularly, keep camphor in water in my bedroom (really good for repelling negativity), salt around the perimeter of my yard, and state the intention that no negativity will enter my space. (Only love can enter and leave). I am an empath, so I have to keep the old shields up constantly. I have clear quartz crystals throughout my home to absorb any negativity, as well.
I regularly take salt baths or showers. They are great for general cleansing and for removing any psychic gunk. Jeez…there are a different million ways….
