The quote highlights the futility of self-justification and the weaknesses of over-explaining oneself, suggesting that one should remain enigmatic rather than revealing every detail of their past or emotions. The emphasis is on the strength found in ambiguity, as the subtlety of a person's gestures and expressions can communicate more powerfully than words. By withholding certain truths, a person retains a form of control and intrigue that can impact others profoundly.
