She had started her life as a beginner at Loreto Novitiate, Darjeeling where she chose to learn English and Bengali (as an Indian language) that’s why she is also called as the Bengali Teresa. Again she returned to the Calcutta where she joined the St. Mary’s school as a teacher of Geography. Once, when she was on her way, she noticed the bad conditions of the people living in the Motijheel slum. She was sent a message from the God on her way to Darjeeling by train, to help the needy people. Soon, she left the convent and started helping poor of that slum. Even after being a European woman, she always wore a cheap white sari.
