Hermann Hesse said this quote
“ Within Siddhartha there slowly grew and ripened the knowledge of what wisdom really was and the goal of his long seeking. It was nothing but a preparation of the soul, a capacity, a secret art of thinking, feeling and breathing thoughts of unity at every moment of life. This thought matured in him slowly, and it was reflected in Vasudeva's old childlike face: harmony, knowledge of the eternal perfection of the world, and unity. ”
