While we understand basics of what Emotions are and how they work, to master understanding of Emotions it is very essential to articulate your experiences accurately and name the Emotion you are feeling. Once we learn to identify and name an experience as an Emotion, it becomes much easier to determine the origin of the Emotion; i.e. to determine which achievement is not in sync with which Desire expected and is far away in which direction. This realization helps us improve our Individual theory making it more realistic.

As an exercise I would urge the reader to do, write beside each Emotion when was the last time it was experienced.
