Leaving it All Behind...

Summarizing:
In the chapter Samsara Siddhartha has become rich and successful. He has many material possessions and now to him everything is a game. Siddartha has fallen from his path and has become greedy, troubled and unhappy. One afternoon he drinks a lot and ends up falling asleep. He dreams that Kamala's bird has died and he throws its body to the street. Siddhartha associates this with him throwing away the good things that are a part of him. He starts reflecting and thinking about his life and how he is living it, and realizes that nothing his life is important to him at all. He decides to leave. Kamaswami sends people to search for him, thinking that someone had kidnapped him.  Kamala knows that he left on his own so she does not look for him, even though she is pregnant with his child.

Quoting:
"Siddhartha wandered into the forest, already far from the town and knew only one thing - that he could not go back, that the life he had lived for many years was past, tasted and drained to a degree of nausea." (page 70)

Paraphrasing:
He wished to rest, to be dead. If lightning would strike him or if a tiger would eat him! If there were poison that could make him forget, go to sleep and never wake up! Was there any sin he hadn't committed or any infamy on his soul he was not responsible for?Was it then still possible to live? Was it possible to take in breath again, to breath out, to feel hunger, to eat, to sleep, or to lie with women again? Was this cycle not exhausted and finished for him?  (pages 70 to 71)
