Since elsewhere I define the emotional content of one's mind to be reactions to external and internal stimuli, unmediated by thought or analysis, the self has to learn to recognise these for what they are. While emotional reactions in many cases can be beautiful things, sometimes they are unpleasant or limiting of future positive experience. This is a very difficult balancing act to pull off.
Remaining open to the fullest emotional range of experience, while recognising it for what it is, can stifle the response before it is even at its full. We must somehow learn to find those places and times where the emotions can run unfettered, and how to reassert some control and direction when appropriate.
