Q. Is there anything one can do about negative emotions when one is in a bad state? A. One must not believe in this bad state. Equally one must not believe in a good state, that it will always remain. Both bad and good state will change. If one believes too much in a good state, a bad state comes and one is not prepared, and as a result one is too much affected. If one identifies too much with one's bad state, one feels that one can do nothing. Bad state or good state, one has to go on—there is only one way.
