There are differences in people’s perception of reality, as there are differences in tastes. The five senses are characterized by the distance from what is perceived: sight is the sense that perceives from the greatest distance and touch is the sense that perceives from the closest distance since it involves contact. The method of developing our perception is called the wisdom of Kabbalah; it teaches us how to perceive unlimited waves. To perceive the unlimited reality, a person needs a new receiver to receive what is external to him, not what is inside him.
