This essay is about imagery and how it helps Siddhartha find his way. Ziolkowkski points out symbols that helps you understand the meaning that Hess was trying to portray. For example, “as the Om hovered over all the voices of the river” (138). There is a self-fulfillment that over comes siddhartha when he passes over the river.

Schoenberg and Lawrence J. Trudeau. Vol. 196. Detroit: Gale, 2008. Literature Resource Center. Web. 5 Mar. 2013. This essay is about how there is more than just learning from straight out of the book. Siddhartha wants to experience the difficulty of learning a lesson. Siddhartha explains, “I want to learn from myself...I want to get to know myself, the secret that is Siddhartha” (646). It is as if he is understanding everything for the first time. Schludermann argues that this is how Siddhartha finds enlightenment.
