Siddhartha by Hermann Hesse
Description (Google Books): Classic novel that has inspired generations of seekers. Blending Eastern mysticism and psychoanalysis, Hesse presents a strikingly original view of man and culture and the arduous process of self-discovery, reconciliation, harmony, and peace.
Recommended by: Rebecca of Lost in Books and Jason W. (personal friend)
Special Notes: Another book to add to my readings to learn more about all religions and spirituality!
