Kalighat, the Home of the Pure Heart (Nirmal Hriday) (formerly Mother Theresa's Kalighat Home for the Dying Destitutes ) is a hospice for the sick, destitute and the dying established by Mother Teresa in Kalighat, Kolkata, India. Before Mother Theresa sought permission to use it, the building was an old abandoned Hindu temple to the goddess Kali, the Hindu goddess of time and change.
