What to say when in fear of afflicting something or someone with one’s eye

The Evil Eye: To look at something and be impressed with it, causing harm to befall it. This “looking” may or may not involve jealousy, and can occur unintentionally, indeed be part of a person’s nature! A person can even inflict harm on himself. From the supplications for the protection against the Evil Eye:

If you see something from your brother, yourself or wealth which you find impressing, then invoke blessings for it, for the evil eye is indeed true’.
