Cimourdain was a pure-minded but gloomy man. He had "the absolute" within him. He had been a priest, which is a solemn thing. Man may have, like the sky, a dark and impenetrable serenity; that something should have caused night to fall in his soul is all that is required. Priesthood had been the cause of night within Cimourdain. Once a priest, always a priest.
Whatever causes night in our souls may leave stars. Cimourdain was full of virtues and truth, but they shine out of a dark background.
