Pi tells us his Auntie Rohini took him to a temple when he was an infant. And that's why he loves all religions.
He loves Hinduism for its rituals and fragrances and vibrancy.
He also really believes in the principle of Brahman saguna and atman, where the divine manifest in the world connects with the divine in human beings. (See Themes: Religion for more.)
Pi gives a wave of the finger to fundamentalists and literalists. He tells a nice story about Lord Krishna and a nice story about a woman in Toronto to illustrate his point. Suffice it to say, Pi likes it when people love God and each other.
