In "Life of Pi" why does Pi become a Hindu? Can you describe Hinduism for me?
One reason that Pi mentions for being a Hindu is that when he was young, too young to even remember consciously, his mother and aunt brought him to Hindu rituals, and the sensory experience of those rituals somehow stuck with him and felt natural and like home to him. He states,
"I am a Hindu because of sculptured cones of red kumkum powder and baskets of yellow tumeric nuggets, because of garlands of flowers and pieces of broken coconut, because of the clanging of bells to announce one's arrival to God..."
He goes on for several paragraphs describing all of the rich, sensory experiences that being a Hindu brings, and explains that all of these are embedded in him, as a part of who he is. So, he is Hindu because the sensory experience of being one feels right to him, and is as ingrained in him as memory.
He states that he is also Hindu because of the rites and rituals that explain the universe to him. He loves the stories, rituals, explanations and rites that the Hindus practice; he is moved by their beauty, by their simple complexity and by their seamless definition of existence. For a more detailed explanation of what Hinduism entails, Pi outlines it in the 3rd paragraph of chapter 16.
I hope that those thoughts help a bit; good luck!
