We tend to understand the eye as an instrument that transfers information to the brain. Similar to the ears its function is intake. According to our teachings, however, the eyes have yet another function. They transfer energy, produced by the Neshama, outward into the world. When you look at an item or a person you are actually transferring some energy of your soul onto that item or person. If you transfer good soul energy it is called ‘Ayin HaTov’. If you transfer negative soul energy it is called ‘Ayin HaRa’. When we feel genuinely happy for another person’s successes and acquisitions we are giving them, through our eyes, a blessing. When we are full of jealousy,covetousness and hate we disadvantage them with an ‘Ayin HaRa’.
