A person can suffer so much from one’s own state of mind, from the actions of other people, or from arguments with others. A person may imagine that someone else is acting against one maliciously; one may weave entire tapestries of fantasy. Then, on the basis of these thoughts which the person created and which one now believes to describe reality, one gets into fights with others or torments oneself. But it is all for nothing.
Surely you wish to lead a good life, a pleasant and a sweet life. Surely you wish to have good relations with the people around you. So recognize your fantasies as the inaccurate portrayals of reality that they are, and throw them away. Look only to G-d. He is the true Reality, and there is no reality independent of Him. He is the Creator and Sustainer of the entire universe, and everything is under His control.
