For it is not physical solitude that actually separates one from other men, not physical isolation, but spiritual isolation. It is not the desert island nor the stony wilderness that cuts you from the people you love. It is the wilderness in the mind, the desert wastes in the heart through which one wanders lost and a stranger. When one is a stranger to oneself then one is estranged from others too. If one is out of touch with oneself, then one cannot touch others. … And, for me, the core, the inner spring, can best be refound through solitude.
