Gautam Lewis is a pilot, photographer and polio survivor. He spent his early years under the care of Mother Teresa. He photographed these sisters praying on the tomb of Mother Teresa in May 2016. "It was very emotional being there," he says.
This woman is a beggar from 24 Parganas, possibly the same district Gautam is originally from. She told Gautam she was also a victim of domestic violence.
Mother Teresa opened Shishu Bhavan, a home for abandoned street babies and children, in Kolkata in 1955.
Today, Shishu Bhavan still provides a home for abandoned and destitute children, including those with special needs.
These orphans, photographed by Gautam in 2009, were rescued by the Missionaries of Charity and taken to Shishu Bhavan. Gautam says the time he spent at the home was tough. "My memories from that period are dark, sad, and lonely," he says.
Gautam photographed this girl begging outside the children's home. "She reminded me of my little sister, Lindi, and my mother, Patricia," he says.
Gautam photographed these sisters, who have stayed together as orphans at the children's home in the care of the Missionaries of Charity. "I probably have brothers and sisters but I don't know who they are," says Gautam.
Gautam says it took him years to be able to return to Shishu Bhavan. "But now I feel as though I'm going back to my fellow siblings, to the brothers and sisters I left behind."

The Home for the Dying and Destitute was the first home Mother Teresa set up when she came to Kolkata. "I've never taken a photograph of a dying person before," says Gautam. "It's something I'll never forget."
A tabla player is pictured at the Home for the Dying and the Destitute. "Even though he was in a place where he was being provided end of life care, he was still happy and musical," says Gautam. "Where there is joy, there is life -- one of the reasons Kolkata is also called the 'City of Joy.'"
