The greatest mystery is not the most distant star; on the contrary, the closer something comes to us and the better we know it, then the more mysterious it becomes for us. The greatest mystery to us is not the most distant person, but the one next to us. The mystery of other people is not reduced by getting to know more and more about them. Rather, in their closeness they become more and more mysterious. And the final depth of all mystery is when two people come so close to each other that they love each other. Nowhere in the world does one feel the might of the mysterious and its wonder as strongly here. When two people know everything about each other, the mystery of the love between them becomes infinitely great. And only in this love do they understand each other, know everything about each other, know each other completely. And yet, the more they love each other and know about each other in love, the more deeply they know the mystery of their love. Thus, knowledge about each other does not remove the mystery, but rather it makes it more profound. The very fact that the other person is so near to me is the greatest mystery.
