Siddhartha is a spiritual tale written by Hermann Hesse and first published in 1922. This is an allegorical novel which deals with the spiritual journey of an Indian boy called Siddhartha during the time of the Buddha.

The word Siddhartha is made up of two words in the Sanskrit language, siddha (gotten) + artha (meaning or wealth). The two words together mean "one who has found meaning (of existence)" or "he who has attained his goals". The Buddha's name, before his renunciation, was Prince Siddhartha Gautama, later the Buddha. In this book, the Buddha is referred to as "Gotama".
