If I would have thought of someone who could've written this kind of book it had to be some humorous atheist foreigner, Sarah McDonald comes to India and leaves swearing never to return but as predicted by a roadside Sadhu she comes back in search of love. It is her journey in search of spirituality where she narrates you her understanding of different religions and beliefs in India.
Her in depth analysis includes almost all the religious beliefs like Hinduism, Sikhism, Buddhism, Jainism, Islam, Judaism, Christianity, Zoroastrianism, and Sufism. More recent targets of devotion, such as Sai Baba, Osho Rajneesh, Yogi Bhajan, Jiddu Krishnamurti and Bollywood stars, are also discussed.
The line I liked the most is "The one thing that can stop a bus, is the king of the road the lord of jungle[traffic] and the top god. The holy cow."
