This is not the Hindu paradise they had crossed the border to join, they said. This is not the India Mr. Modi promised them.

Mr. Bheel is wracked by doubt, the same doubt his grandfather had when he chose to keep the family in Pakistan during partition. Did he make the right choice?

He left his home and siblings in Karachi, trading a lucrative job as an administrator of a medical clinic there to live as a migrant in India. His medical diploma, one of the few possessions he brought with him, hangs proudly on a wall, although it is not valid in India. He struggles to make ends meet here.

“You take these decisions sometimes out of excitement for what your life could be,” Mr. Bheel said, his daughter cuddling beside him on a bench. “Then you arrive and realize it’s much different on the ground.”

Mr. Bheel looked on as his wife struggled to contain rainwater leaking from the ceiling, after a monsoon swiftly obliterated the sunny sky. Eventually she gave up, running out of pots and buckets.

“Maybe this wasn’t the right decision for me,” he said. “But maybe my children will look back and say, ‘My father made the right choice.’”
