Rabbi Pinto explains: How to neutralize the evil eye easily? - Walla! Judaism. In his class in Miami, the Rebbe Rabbi Yosiah Pinto explained the destructive power of the good eye.
If we are strong enough in our hearts and minds, and we don't let anyone outside influence us - then No evil eye will control us, Rabbi Pinto said. The intention is not to be indifferent to the environment and detached, but to be strong and not let anyone enter our thoughts and feelings.
