Siddhartha question

Siddhartha's journey begins with confusion and emptiness in the wake of many questions Siddhartha has regarding the Brahman practices and his religion as a whole. Despite being one of the most highly praised students of his group Siddhartha cannot help but feel that the answers to his question do not lay within his system of belief. In a conversation with Govinda, Siddhartha shares all of his concerns saying, "the ablutions were good, but they were water; they did not wash sins away...where did his eternal heart beat if not within the self"(3-4)?

Although Siddhartha's questioning ultimately is the catalyst for his journey, it also leads him to the brink of suicide. In what ways did Siddhartha's never ending search for answers both hinder and foster Siddhartha's ability to finally achieve peace at the end of the novel?
