Ordinarily there exist many barriers between one person and another, such as prejudice, hatred, reserve, remoteness and all aspects of duality. A person considers another his greatest friend in the world if he realizes that the other understands him. There is nothing that brings two people closer together than understanding. And what is this comprehension? It is trinity with unity. Often one wonders, "Why do I not understand this person?" But one does not realize that one creates oneself the barriers which separate one person from another. If these barriers are not created, the soul has freedom to see and nothing can stand in its way. Do you think the sages and saints try to see the thoughts of other people? Not at all; that does not concern them. But the thoughts of another person manifest themselves to the saint. Why? Because there is no barrier. This barrier creates duality.
