Mark 7:20 - 23 says:
But he said that the things which forth from a man, they make a man common.
For from within out of the heart of men proceed evil cogitations, adulteries, fornications, murders,
Thefts, avarices, wickedness, guile, impudicities, an evil eye, blasphemy, pride, foolishness.
DR Bible

So we know from Jesus Christ that there is such a thing as an evil eye and it is not a fable. From what I understand is that if you look on someone with envy you can give that person an evil eye which is a kind of curse on that person so that bad things will happen to them. Is this correct? I know that some translations have here envy instead of an evil eye possibly because incredulity. I remember reading (on Arturo Vasquez's blog) that some Mexicans when they look at a beautiful child with envy they make sure to touch the child because they believe that looking at a child with envy can give them the evil eye and that touching the child somehow counteracts this. If anyone knows anything about the evil eye I am very interested in learning about it.

If this was discussed in an earlier topic, I apologize.

The evil eye is a kind of curse put on a child, livestock, crops, etc., by someone who has the "evil eye." There does not seem to be any particular reason why some people are born with and others without the evil eye. The curse is usually unintentional and caused by praising and looking enviously at the victim. In Sicily and southern Italy, however, it is believed that some people--jettatore-- are malevolent and deliberately cast the evil eye on their victims. Belief in the evil eye is not necessarily associated with witchcraft or sorcery, though Evil Eye was something Church inquisitors were instructed to look for. Pope Pius IX was reputed to be a jettatore, not because it was thought he was malevolent but rather because it seemed that disasters fell upon persons and places he had blessed.

The superstitious belief in the evil eye is ancient and widespread, though certainly not universal. It is thought to have originated in Sumeria. Its origins are obscure but the belief may have its roots in fear of strangers or other social concerns and simple post hoc reasoning, e.g., praise is given or a stranger passes and later a child is sick or the crops fail. Various rituals have developed to counteract the effects of the evil eye, such as defusing the praise, putting spit or dirt on a child who is praised, averting the gaze of strangers, reciting some verses from the Bible or the Koran, etc. The belief is especially prevalent today in the Mediterranean and Aegean, where apotropaic amulets and talismans are commonly sold as protection against the evil eye. Some folklorists believe that the evil eye belief is rooted in primate biology (dominance and submission are shown by gazing and averting the gaze) and relates to our dislike of staring.

The evil eye is known as ayin horeh in Hebrew; ayin harsha in Arabic, droch shuil in Scotland, mauvais oeil in France, bösen Blick in Germany, mal occhio in Italy and was known as oculus malus among the classical Romans.

  So belessings must be guarantees of success?

Secs of State Antonelli and Rampolla were both alleged to possess an 'evil eye' with which they excecised a nefarious influence over the Pope-- just a bunch of crap.
