Throughout his life, Siddhartha has gone through many ups and downs. In order to gain one thing, he has to give up others. One could question whether what he is trying to achieve is worth what he is giving up. He wants to find self so he can be content, but maybe if he would recognize the good things around him, he would be happy. After following Siddhartha on his journey he learned that Nirvana doesn't come cheap. I thing he learned this through his encounters with Govinda, Vasudeva, and his son.
Govinda plays a vital role in Siddhartha's life. He is there at the beginning. He is very good friends with Siddhartha throughout his childhood, and even decides to become a Samana. Siddhartha realizes the dedication that Govinda has for him. Siddhartha realizes that Govinda really does love him. Siddhartha decides to abandon this love to find self. Siddhartha encountered a really good friend during his journey. His name was Vasudeva. This character helped him find self. Vasudeva was a simple man and was a teacher to Siddhartha. Siddhartha's son was very much like himself. He was defiant. This made Siddhartha mad and his son decided to leave.
In conclusion, Siddartha tried to find self, but ended up losing other things in return. I think that Siddhartha didn't find nirvana. He may have found self, but he gave up other things like love. I don't know the exact definition, but I think that nirvana involves understanding love, and excepting it.
