Hermann Hesse said this quote

One knew nothing. One lived and walked about on the earth or rode through the forests, and so many things looked at one with such challenge and promise, rousing such longing: an evening star, a bluebell, a lake green with reeds, the eye of a human being or of a cow, and at times it seemed as if the very next moment something never seen but long yearned for must happen, as if a veil must drop from everything. But then it passed, and nothing happened, and the riddle was not solved, nor was the secret spell lifted, and finally one became old... and perhaps one still knew nothing, would still be waiting and listening.
