A Cloud Still Hangs Over Bhopal by Suketu Mehta in New York Times is the best article that I read so far about Bhopal tragedy.
All over India, when misfortune strikes — when a child is ill, for example — people burn chilies to drive away the evil eye. The gas smelled like chilies burning, and people said to one another, it must be a powerfully evil eye that’s being driven away, the stench is so strong.
Fleeing the gas, the Bhopalis clutched their children. Some babies fell, gasping, and their parents had to choose which ones to carry on their shoulders. One image still comes up over and over in their dreams: in the stampede, a thousand people are stepping on their child’s body.
