About the ending.

ATTENTION!!!  This article contains spoilers! If you don't want to know how the story ends before the reading, you should skip it!

    Now I've read all the novel up to the end. And I'm surprised, because nobody could guess that there are two completely different stories in this novel.
    After the great journey on the boat with all this problemes with the tiger, the boat finally reaches a coast of Mexica. The tiger went far inland, but Pi was saved by locals. Representatives of the shipping company came to the hospital to Pi, but they didn't belive in the story, which he told them, how he spent so much time with wild animals,  and after some time, only together with the tiger. That's why he told them a different story. The story without animals at all, which was more realistic. And which was a real truth. There was no tiger, the guy created him in his mind not to go mad! And the second story he told after the rescue is more plausible.
    The main idea is that people always want to believe in something because the belief is necessary to survive. If Pi belived in a real story with a cannibalism and murders which he told at the end, he would forever remain the intimidated, morally destroyed person, with the nightmares and bad memories. But he made up all these animals to make it easier to survive the event. The tiger is his fear, his pain. The tiger is himself. He tamed the fear, learned to live with it. All this story was his own invention. He made up and belived in it himself to remain the normal person. All his family was with him on the boat, but it was difficult for him to watch how the cook killed all his family and he was imagining that the hyena is the cook, who was offending  their family even on the board. The monkey is the boy's mother,whom he was unable to save from the cruelty in the boat, the zebra is one of the sailors.
    It's impossible to provide my own ending here, the story is too complicated and I need some time just to comprehend the reading. And in such stories there is no other way - he would always be resqued, but how he spent all the time in the ocean, whether there were animals or humans on the boat - that is the question.
