Some Jews believe that a "good eye" designates an attitude of good will and kindness towards others. Someone who has this attitude in life will rejoice when his fellow man prospers; he will wish everyone well. An "evil eye" denotes the opposite attitude. A man with "an evil eye" will not only feel no joy but experience actual distress when others prosper, and will rejoice when others suffer. A person of this character represents a great danger to our moral purity, according to some Jews.
