In what way is siddhartha now like a child?

In Kamaswami’s employ, Siddhartha becomes wealthy and enjoys Kamala’s intimate company. He lives this way for many years, becoming more and more successful at business. At first, while business is all a game, he feels superior to those who pursue worldly pleasures and riches. Gradually, however, he, too, falls under the spell of possessions. He looks and acts like a wealthy merchant, wearing the finest clothes, eating rich food, entertaining dancers, and gambling, but he finds that the spiritual voice within him has died. Even his continued relationship with Kamala brings him little peace.
Some twenty years after his arrival, he notices that Kamala’s face has wrinkles and his own hair has traces of gray. Siddhartha begins to have dreams that suggest the time may have come to move on. In one dream, he recalls a conversation with Kamala in which she expresses interest in Gotama, but Siddhartha dissuades her from seeking him out. In another dream, he finds the rare songbird Kamala keeps in a cage has died. He throws it out into the street, as though he discards all that is good and of value in his life. When he wakes up, he feels death in his heart. The inner voice that had prompted him to become a Samana, to turn away from the Buddha, and to face the unknown has been silent for a long time.
Distraught over these dreams, Siddhartha retreats to a pleasure garden to meditate. He considers his life in the city. The life he has made by apprenticing himself to Kamaswami seems only a diversion from his path to enlightenment. His nights of drinking, dancing, and eating have yielded a pleasant oblivion but have produced nothing. His relationship with Kamala has given him pleasure and taught him much about love, but it cannot continue forever if he aims to achieve enlightenment. He realizes that he has been playing at the game of Samsara, the cyclical path of normal life in which one lives, suffers, and dies. While it is important for him to have played this game, he does not need to keep playing it forever. He leaves the city in despair, without informing anyone of his departure. When Kamala learns of his disappearance, she frees her songbird from its golden cage. From this day on, Kamala accepts no more lovers, and she discovers she is pregnant with Siddhartha’s child.
