Kalighat, the Home of the Pure Heart (Nirmal Hriday)[1] (formerly Mother Teresa's Kalighat Home for the Dying Destitutes) is a hospice for the sick, destitute and the dying established by St. Mother Teresa[2][3] in Kalighat, Kolkata, India. Before Mother Teresa sought permission to use it, the building was an old abandoned Hindu temple to the goddess Kali,[4] the Hindu goddess of time and change. It was founded by St. Mother Teresa on her 42nd birthday in 1952,[5] two years after she established Missionaries of Charity in Kolkata.
