historically, the evil eye was what people called when someone either looked at them funny, or a person had one eye different from the other. [one blue eye, blind in one eye...] people were afraid that if the person with the eye looked at you, they could curse you. this is 95% superstition.
how to do the 'evil eye' is pretty simple. since magic is intend and focus, if someone has REALLY upset you, have you ever glared at them and thought something like 'i wish you would go away!' or something similar? that's the evil eye. if you focus on someone and concentrate on cursing them, it can happen. it takes time and practice, and i don't know of anyone dying from the evil eye, just having bad luck. personally, i don't think i ever cast it.
what do you mean? someone can curse you, how you get one eye different, or how can you cast it?
the eye thing is from birth, normally if you were born a twin but the cell don't divide so it's one person [if memory serves, correct me if i got that wrong] blindness is normally genetic, but you could get a cataract from years of smoking causing blindness in one eye. or you could just wear a contact lens.
curses, in my opinion, are more to do with a placebo effect. yes you can curse someone, and yes you too can be cursed, but a curse is only as strong as a person makes it out to be. while the caster feeds it energy to send out the curse, the cursed person can also feed it by blaming everything bad on it, and getting worked up. this being said, you could be cursed and not know it, someone could curse you and you fall down some stairs. you can chalk that up to being clumsy. normally [depending on the type of curse] things change rapidly for you, a series of bad luck, sudden sickness, and so on. also, you could curse yourself, say, by thinking you're cursed. every time something bad happens, say it was a curse, subconsciously, you're feeding energy into something that isn't there, until you're cursed for real.
how to cast it, like i said, glare at someone, focus all your hatred at them and think 'i curse you' or 'i hope you get hurt' or something along those lines.
I think Neko said it. The evil eye is basically cursing someone as little or as much as to greatly, with an amount of hatred or frustration with a projection, in mind and of the mind.
You see, your actions just don't amount to the things you do, they can also amount to the things you "do" in your mind. In all sake of explanation, the physical follows suit along with or after the spiritual, and vise versa in some beliefs. "You get it coming and going, or also going then coming."
What strengthens any magickal endeavors and workings, in my opinion, is your skill set on your mediations, because if you can imagine something there, then it is there, but it is like how well can you send it and for how long?
It is like that saying or belief that mediation basically manifests things in the universe for a person, or what they visualize is more likely to manifest. One Wiccan priest told me, in spell casting you have the tools to move a boulder, and you work your magick with your correspondences, and it is with those tools that makes it easier to move that boulder, as the beings in the spiritual go in as they see fit. As he said compared to simply meditation, it's less tedious, but the same concept as things in the spiritual will say, oh look lets go help that person manifest what he or she is visualizing.
Then there is the will power behind the evil eye, not only do you have to have the spiritual strength to basically drop a bomb on the psychic plane, you gotta have the will. The evil eye is usually said to be in those who have strong based emotions, and have the gift of powerful projections. Like all emotions, we can sometimes not be able to control ourselves. Then it gets into philosophy. Lol!
