Pi is a believer in the fullest sense of the word: he uses his rational intellect to take him as far as he can go, and then he takes imaginative leaps. However, Pi has a hard time with his faith; he doesn't believe in only one religion, but three. The similarities and differences comparing the book and the movies interpretation for Pi's love of the three religions is significant because we're losing the focus on religion throughout Pi's journey. Losing this information changes your interpretation of how Pi's survival relates to his religious background, which could lead to a misapprehension of the theme the author is trying to get across. The book contributes more detail about Pi's spiritual journey such as, when he goes to the church, and talks to us parents. .
There are not a lot of similarities between the Life of Pi book and movie; however, Pi's family does confront him about his religious beliefs. In the book, Pi asks his father for a prayer rug, and that is what sets off an argument about why Pi believes in three religions, and then how Pi should only believe in one religion, preferably Hinduism. In the movie, Pi's father also confronts Pi about his choice in religion. In both stories, Pi's father tell Pi that he needs to pick on religion, as there is one nation, and one world. This is relevant because Pi's father wants Pi to be one with the universe, have that one belief in the world. However, Pi's world is so different; it's too extreme. Which is why towards the middle of the story, Pi sort of started to blend these three religions together. .
Even though there may be a few similarities between the book and movie, the movie cuts out one who scene between Pi's encounter with the three religious mentors. Because this scene is cut out of the movie, we sort of lose the focus on religion throughout the story. In the book, Pi's religious mentors all come across Pi and his parents at the same time at a restaurant.
