how do you feel about personal superstitions, developed through individual experience? in my household, before bed, i ask for blessings from my parents and return the sentiment. i'm not pious, nor even religious in the standard sense, but whenever i forget to or don't have the chance, i feel terribly anxious, like something terrible will happen to them/me overnight. i know this comes off as irrational, but it makes me feel safe.
I think they serve a purpose, which I hope is mostly positive. I have my own as well. Some might be seen as prayers or silent meditations. They help me feel better and cope with stressful situations. I don't tell anyone about these or force anyone to do them. Is is irrational? Maybe, but it brings me peace without harming anyone or making the world a worse place to live in.
