Indian to the Core, and an Oligarch

Mr. Gandhi was a scrawny ascetic, a champion of the village, a skeptic of modernity and a man focused on spiritual purity. Mr. Ambani is a fleshy oligarch, a champion of the city, a burier of the past and a man who deftly — and, some critics say, ruthlessly — wields financial power. He is the richest person in India, with a fortune estimated in the tens of billions of dollars, and many people here expect that he will be the richest person on earth before long.
