It dates back to a day in 1987 when Punjab was burning. I read about a spastic girl and her parents being killed in Amritsar. It disturbed me and I decided to march to Amritsar from Mumbai on foot. It was part of Gandhian philosophy that if your people are doing wrong you punish yourself. Gandhiji would fast; likewise, I decided to walk and inflict some pain on myself. It was a way of sharing the pain.
