I have recently inherited a mirror that has been handed down from a couple generations at least. My siblings refused to take this mirror for themselves but would rather see it destroyed. For as far back as I can remember my mother would use this mirror to curse people by placing photos of certain people on it upside down in order to put a hex in them or intend misfortune. When I was a kid I use to search the mirror and find the upside down pictures behind other pictures and take them off the mirror. I did this for years thus identifying my mother as an evil person intending harm to others including friends and family. The mirror was eventually handed down to my brother who wants no part of it and has given it to me. My question is if it has been previously used for bad intent, is there something I could or should do to purify or neutralize it? I'm not as afraid of it as some I know because in my mind I was always the one trying to stop the bad intent thus any curse it was used for I don't see fit for myself. Any suggestions?
