There are two trees, each yielding its own fruit. One of them is negative . . . it grows from lack of self-worth and its fruits are fear, anger, envy, bitterness, sorrow - and any other negative emotion. Then there is the tree of positive emotions. Its nutrients include self-forgiveness and a correct self concept. Its fruits are love, joy, acceptance, self-esteem, faith, peace . . . and other uplifting emotions.
We must believe that "emotion recollected in tranquillity" is an inexact formula. For it is neither emotion, nor recollection, nor without distortion of meaning, tranquillity. It is a concentration, and a new thing resulting from the concentration of a very great number of experiences which to the practical and active person would not seem to be experiences at all; it is a concentration which does not happen consciously or of deliberation. These experiences are not "recollected" and they finally unite in an atmosphere which is "tranquil" only in that it is a passive attending upon the event.
We might remind ourselves that criticism is as inevitable as breathing, and that we should be none the worse for articulating what passes in our minds when we read a book and feel an emotion about it, for criticizing our own minds in their work of criticism.
An adventure is never an adventure while it's happening. Challenging experiences need time to ferment, and adventure is simply physical and emotional discomfort recollected in tranquillity.
