Chaucer asks his readers to thank Jesus if anything in his work pleases them and blame Chaucer himself for whatever does not. He asks for prayers so that Christ will forgive him for his writings that have concentrated on worldly things and have been inappropriate, including many of his tales of Canterbury. He thanks Jesus and Mary for the works of morality and devotion that he has composed, and he asks for grace to repent of his sins and save his soul.
