Looking for a Miracle

According to a news report from India, “At least 50 people in Kottayam district have reportedly lost their vision after gazing at the sun looking for an image of Virgin Mary.”

My first reaction to news like this is that it confirms my prejudice that the human race is, generally speaking, insane. Still, I wonder how religious examples of self-harming behavior are different from more secular examples. No small number of people have lost their shirt investing in a stock market bubble, which with hindsight can look pretty stupid. Is it generally the religious examples that look more drastic or weird in some special way? Am I merely showing my secular culture when I think so?
