One cannot always tell what it is that keeps us shut in, confines us, seems to bury us, but still one feels certain barriers, certain gates, certain walls. . . . Do you know what frees one from this captivity? It is very deep serious affection. Being friends, being brothers, love, that is what opens the prison by supreme power, by some magic force. But without this one remains in prison. There where sympathy is renewed, life is restored.
— Vincent Van Gogh, Holy Clues by Stephen Kendrick
