I'm just starting with magick (knowingly at least) and I want to place some protection in my house that is under the influence of an evil entity. Two other family members and I have been using visualization, prayers, and holy water (my family is Christian) for months but if one of us forgets to do it even one night, the entity attacks and I'm worried about my family, especially because there are young children. I don't think I should go for a banishing spell yet as I'm not experienced enough and don't want to mess up because of how aggressive this entity is. So how often should I reinforce the protection? And can I keep cleansing the house (say, weekly) without affecting the protection I place?
