Traditional sources abound with exhortations to avoid the "evil eye" [Bava Metzia 107b and 85a, Pesachim 50b, Berakhot 55b, Bava Batra 2b and 141a]. The Talmud asserts flatly: "Damage caused by looking is also damage." [Bava Batra 2b]
But there is also the "good eye" to counterbalance the evil eye. It belongs to one who is satisfied with what he has and does not covet what others have. The Mishna says:
Whoever possesses these three things, he is of the disciples of Abraham, our father : ... a good eye, a humble spirit and a moderate appetite. [Avot 5:19]
Should you seek people who have a "good eye" (for example, your parents, who will rejoice at your good fortune and not envy it) so they may reinforce your blessings and perhaps invite more of the same?
I did not find such encouragement in the Sources -- only exhortations to avoid the evil eye. Perhaps the answer is obvious. But if so, isn't it also obvious in the case of the evil eye?
