"<p>Remember that the condition of your body, your stomach, appetite or its appeasement, fatigue, illness, all these transform, not transform, but raise to the highest stage or descend to the lowest stage your state of mind, your attitude towards life . When you are in the ecstasy of joy, moved by the goodness of life, when you are sad and melancholy. When you love everyone, when you love no one or at least refrain from loving. Remember this, and do not attribute to that state of elation or depression the importance of your true state. And the true state of your "I" is the central, middle one, the one in which you enjoy the state of elevation, strive to maintain it, do not believe in the state of depression and try to overcome it. It is important that this center point always moves up, never down. Thank God it exists.</p>"
