DELHI, India (BP) -- Delhi is a sprawling, energetic intersection of old and new, wealth and poverty, religion and science. People from across southern Asia come for jobs, education and asylum. Delhi is massive, teeming and heaving with people. Even though I've lived and worked in India and elsewhere in the region for years, I am easily overwhelmed by this city of nearly 17 million people and want to know it better. Join me on three prayer journeys in Delhi.
