Aspects of the culture reflected in the story. 

    I'll begin with the fact, that Pi is a multireligious person, he sees no difference between the love of God among Muslims or Hare Krishna, between the faith in Muhammad and the faith in Jesus. But they are three world religions, each of them has its own history, which in turn shows the difference in cultural aspects. There are some national-psychological features of representatives of different religions. The world perception,  attitude, mental aspirations, the mode of action and the spirit depend on religious priorities.
    Though Pi had his own national identity, it is difficult to talk about his mentality. That is why there could be some misunderstanding among readers of different nationalities, as everyone perceives a book in the own way, from the own vision of the problem.
But inspite of that, this book still will attract public's attention, because Pi is an Indian, we don't know much about this culture. And uniqueness and mystery of India is one of the reasons for reading this book, because it is one of the possibilities to learn more about the culture through a representative.
So, if compare Pi's culture to my own one, there are some differences.  Indians have their own ideal of feminine beauty. They considere that it's beautiful when all the parts of the body are proportional. Also ideal is a small face, so women use many complex decorations and natural flowers that helps to create the illusion of a small face.
    Another fact is that a Bengal tiger - the national animal of India. Probably that's why the tiger took so much place in this book for Pi. If you delve into the history, we can see that in ancient times in India lived  4 species of big cats: leopards, tigers, lions and cheetahs. A tiger captures best of all the essence of India. Freedom-loving, strong and wise, it is perfectly symbolizes the Indian people, who for centuries have often had to fight for their independence.
    To sum up, I can say, that there would not much serious difficulties to read this book, and you even can learn more about the culture of India.
