In the beginning one may need to control emotions but eventually the conditioning that triggers strong emotions and acting will fade away and a cool calm contentedness will take the place of the hot burning negative emotions and feelings. I have had some experience with the coolness of equanimity...it is awesome! No longer do my emotions lead me around by the nose, well most of the time anyway ;-) at least I don't throw my shoes at when I get angry at the family not putting their stuff away in its proper place....hahahaha
