I have two altars in my house, Im a Pagan/Luciferian and Gnostic. So my Statues have been possessed by negative bad spirits, and I personally do not mind working with evil spirits, as long as they do not threaten my personal mental health and other stuff. Any advice on any spells which can help me restore the statues on my altar would be much appreciated. Thanks.
Have you thought about doing just a classic cleansing ritual? Id suggest burning some sage and invoking Michael to remove all unwanted spirits from your home. Also to clean your entire house top to bottom, leave no stone un turned, including cleaning your altars and bathing the statues, while bathing them focus on your heart chakra. Really focus that cleansing mentality.
