What someone else says cannot really annoy or irritate you unless you permit it to disturb you. the only path by which another person can upset you is through your own thought. if you get angry, you have to go through four stages in your mind . you begin to think about what was said. you decide to get angry and generate an emotion of rage.
Then you decide to act. perhaps you talk back and react kind. as you see, the thought, emotion, reaction and action all take place in your own mind.
what does it mean to be emotionally mature?
It means that you move beyond the natural, but childish, tendency to respond negatively to the criticism and resentment of others. no one likes to be criticized or belittled. however, we have the ability to choose how to react when it happens. the mature choice is to refrain from responding in a similarly negative way. responding in kind means to descend to the level of belittling criticism and to become one with the negative atmosphere of the other. identify yourself with your own aim in life. do not permit any person, place, or thing to deflect you from your inner sense of peace , tranquility, and radiant health.
