But if then you notice that it is great, rejoice because of this, for what (ask yourself) would solitude be that had no greatness. There is but one solitude, and that is great, and not easy to bear, and to almost everybody come hours when they would gladly exchange it for any sort of intercourse, however banal and cheap, for the semblance of some slight accord with the first comer, with the unworthiest… But perhaps those are the very hours when solitude grows, for its growing is painful as the growing of boys and sad as the beginning of spring-times. But that must not mislead you. The necessary thing is after all but this: solitude, great inner solitude. Going into oneself and for hours meeting no one — this one must be able to attain.

Rainer Maria Rilke (1875 – 1926)
