It is unthinkable that one could keep the doors and windows of one’s house open for thirty long years. Only a really fearless hermit can do it. The Bishop keeps the doors and windows open so that the poor and the needy could come anytime to his house. It reveals that his mind and heart are open. He is so generous and magnanimous that he attaches no importance to any material thing. He sells his estate, his silver salt-cellars and many others valuable things to help the poor. Though he cherishes his silver candlesticks, he readily gifts them to the convict.
Earlier in the play, Persome reminds the Bishop how people take undue advantage of his generosity. Even the convict mocks at him for leaving his windows and doors open. But the Bishop does not have a second thought at what he does.
