دَع التَکاسُل تَغنَم فَقَد جَری مثلُ       که زاد رهروان چستی است و چالاکی

                     Catharsis or Katharsis is a Greek word meaning "emotional cleansing". It describes an extreme change in emotion, occurring as the result of experiecing strong feelings (such as sorrow, fear, pity, or even laughter). It has been described as a "purification" or a "purging" of such emotions.

The term Catharsis has also been adopted by modern psychotherapy, particularly Freudian psychoanalysis, to describe the act of expressing, or more accurately, experiencing the deep emotions often associated with events in the individual's past which had originally been repressed or ignored, and had never been adequately addressed or experienced.
