"Within Siddhartha there slowly grew and ripened a 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." -Hermann Hesse
Another good one, "From that hour Siddhartha ceased to fight against his destiny. There shone in his face the serenity of knowledge, of one who is no longer confronted with conflict of desires, who has found salvation, who is in harmony with the stream of events, with the stream of life, full of sympathy and compassion, surrendering himself to the stream, belonging to the unity of all things."
