"Murmuring Om, he laid his head on the tree roots and sank into a deep sleep" (90)

"Siddhartha was transitory, all forms were transitory, but today he was young-the new Siddhartha-and he was happy" (100)
Siddhartha comes to his senses and realizes what was wrong with him. He discards his previous life and awakes as a reborn man. (Siddhartha's revelation)
Siddhartha meets his childhood friend, Govinda, again. Siddhartha recognizes him, but Govinda doesn't. When discovering who Siddhartha is, Govinda questions why he is dressed as a rich person. Siddhartha tells him how was a rich person, but no longer is. He shows how he has discarded his past life.
