Author's Conclusion to Pilgrim's Progress Part 1

In the conclusion, the narrator says that he has told his dream and invites the reader to interpret it. Though he warns of the dangers of interpreting his dream wrongly, the narrator also cautions against playing around with the obvious surface content of the tale, being entertained by it rather than instructed. He says that, just as no one throws away an apple to save the core, so too must no one throw away the essence of his story to save its inessential parts.
