Sishu Tirtha, however, is not a regular orphanage. "The idea of setting up this institution was born after a visit to an SOS Village in Salt Lake (Calcutta) many years ago. I was impressed by the SOS Village concept of providing children not just a place to stay and study, but also a family to belong to. I’ve tried to replicate that here," recalls Thakur, who is distantly related to the Nobel laureate.
