We live in a world full of envy. It is its nature to blind us to all the good things we already have.
Invidia (which “envy” is derived), is related to videre, “see”. We always have eyes looking at us, judging us, with jealous.
The Romans called envy “the evil eye”, they believed that if another person look at you with penetrating malice it could harm you. In many cultures, receiving this ill-seeing may cause misfortune or even serious injuries.
