Hermann Hesse said this quote

After having been standing by the gate of the garden for a long time, Siddhartha realised that his desire was foolish, which had made him go up to this place, that he could not help his son, that he was not allowed to cling him. Deeply, he felt the love for the run-away in his heart, like a wound, and he felt at the same time that this wound had not been given to him in order to turn the knife in it, that it had to become a blossom and had to shine.
