One day in Srirangam, Sandhya took me on a tour of the Sri Ranganathaswamy Temple. She used to live with an aunt in the complex. It is the largest (functioning) Hindu temple in the world, covering 156 acres. This was the only Vaishnavite temple we visited, because Krishnan’s family is Shaivite. Walking along, I noticed this small shrine festooned with a bunch of padlocks.
