Superstitions are mostly people who are uneducated and fearful. In my experience anyway. It goes deep here, cause of the local Native American lores too. What I do not understand is those who claim to be Christian, being superstitious. There are no salt fairies, no malevolent, or nice force that does things for or against you at the whim of nothing other than a person sees a black cat, walks on a crack in a sidewalk or you accidentally knock the salt over. Jesus came to free us from the bondage of man made junk and to show us that the only one who is out there for us is God.
