Siddhartha is the most famous and influential novel by Nobel prize-winning author Hermann Hesse. The book was written in German, in a simple, lyrical style and became influential during the 1960s. Set in India, Siddhartha is the story of a young Brahmin's search for ultimate reality after meeting with the Buddha. His quest takes him from a life of decadence to asceticism, through the illusory joys of sensual love with a beautiful courtesan, and of wealth and fame, to the painful struggles with his son and the ultimate wisdom of renunciation. Hermann Hesse (July 2, 1877 – August 9, 1962) was a German poet, novelist, and painter. His best-known works include Steppenwolf, Siddhartha, and The Glass Bead Game, each of which explores an individual's search for authenticity, self-knowledge and spirituality. In 1946, he received the Nobel Prize in Literature.

シッダールタとは、釈尊の出家以前の名である。生に苦しみ出離を求めたシッダールタは、苦行に苦行を重ねたあげく、川の流れから時間を超越することによってのみ幸福が得られることを学び、ついに一切をあるがままに愛する悟りの境地に達する。――成道後の仏陀を讃美するのではなく、悟りに至るまでの求道者の体験の奥義を探ろうとしたこの作品は、ヘッセ芸術のひとつの頂点である。
