In Hesse's novel, experience, the totality of conscious events of a human life, is shown as the best way to approach understanding of reality and attain enlightenment—Hesse's crafting of Siddhartha's journey shows that understanding is attained not through intellectual methods, nor through immersing oneself in the carnal pleasures of the world and the accompanying pain of samsara; rather, it is the completeness of these experiences that allows Siddhartha to attain understanding.
Thus, individual events are meaningless when considered by themselves—Siddhartha's stay with the Shramanas and his immersion in the worlds of love and business do not ipso facto lead to nirvana, yet they cannot be considered distractions, for every action and event gives Siddhartha experience, which in turn leads to understanding.
A major preoccupation of Hesse in writing Siddhartha was to cure his "sickness with life" (Lebenskrankheit) by immersing himself in Indian philosophy such as that expounded in the Upanishads and the Bhagavad Gita.[2] The reason the second half of the book took so long to write was that Hesse "had not experienced that transcendental state of unity to which Siddhartha aspires. In an attempt to do so, Hesse lived as a virtual semi-recluse and became totally immersed in the sacred teachings of both Hindu and Buddhist scriptures. His intention was to attain to that 'completeness' which, in the novel, is the Buddha's badge of distinction."[3] The novel is structured on three of the traditional stages of life for Hindu males (student (brahmacharin), householder (grihastha) and recluse/renunciate (vanaprastha) as well as the Buddha's Four Noble Truths (Part One) and Eightfold Path (Part Two) which form twelve chapters, the number in the novel.[4] Ralph Freedman mentions how Hesse commented in a letter "[my] Siddhartha does not, in the end, learn true wisdom from any teacher, but from a river that roars in a funny way and from a kindly old fool who always smiles and is secretly a saint."[5] In a lecture about Siddhartha, Hesse claimed "Buddha's way to salvation has often been criticized and doubted, because it is thought to be wholly grounded in cognition. True, but it's not just intellectual cognition, not just learning and knowing, but spiritual experience that can be earned only through strict discipline in a selfless life".[6] Freedman also points out how Siddhartha described Hesse's interior dialectic: "All of the contrasting poles of his life were sharply etched: the restless departures and the search for stillness at home; the diversity of experience and the harmony of a unifying spirit; the security of religious dogma and the anxiety of freedom."[7] Eberhard Ostermann has shown how Hesse, while mixing the religious genre of the legend with that of the modern novel, seeks to reconcile with the double-edged effects of modernization such as individualization, pluralism or self-disciplining.[8]
The character Siddhartha honors the character Gotama (Gautama Buddha) by not following him in person, but by following Gotama's example. This is an example of the Theravada tradition evolving later, but modeled by the Buddha's philosophy and values.
