A person may be unconsciously if intermittently aware of a sharp fall, a terrible contrast between what he once was and now is. There may be a resultant feeling of unused potentiality, of not being in his original status, of not having found himself. These moods of thought and fits of feeling are most potent after he lets himself sink too deeply and too vehemently into personal life, personal emotions, and the dynamism which may be a part of his natural temperament. What may such a one do about his trouble? He is a sick soul and needs a soul physician. However, it is most advisable that during the periods of productive effort, of electrifying energy, he should try to moderate his actions, deliberately tone down his feelings, and calm his thoughts. This stormy intensity should be displaced by abruptly remembering its existence and breaking off into momentary self-recollection, standing back suddenly from his tremendous immersion in the egoic life and holding in his thought its transience and evanescence. Such concentrated power is a tremendous asset when directed rightly, but he has to pay the price of its possession when the personality is unintegrated. He should not work too hard, neither in quantity nor so intensely in quality. He should practise habitual relaxation in the very midst of his productive periods.
