Siddhartha - Hermann Hesse

Siddhartha is an allegorical novel by Hermann Hesse which deals with the spiritual journey of a boy known as Siddhartha from the Indian Subcontinent during the time of the Buddha.
The word Siddhartha is made up of two words in the Sanskrit language, siddha (achieved) + artha (meaning or wealth). The two words together mean "he who has found meaning (of existence)" or "he who has attained his goals". The Buddha's name, before his renunciation, was Prince Siddhartha Gautama. In this book, the Buddha is referred to as "Gotama".
Sl.ower, he walked along in his thoughts and asked himself: “But what is
this, what you have sought to learn from teachings and from teachers, and what they, who have taught you much, were still unable to teach you?” And he found: “It was the self, the purpose and essence of which I sought to learn. It was the self, I wanted to free myself from, which I sought to overcome. But I was not able to overcome it, could only deceive it, could only flee from it, only hide from it. Truly, no thing in this world has kept my thoughts thus busy, as this my very own self, this mystery of me being alive, of me being one and being separated and isolated from all others, of me being Siddhartha! And there is no thing in this world I know less about than about me, about Siddhartha!”
