In order for the spells to be broken, Don Quixote and Sancho must go to the Kingdom of Candaya to battle Malambruno, as he is sending a flying wooden horse to transport them to meet him. Sancho does not understand why he must suffer to rid the duenna’s of their beards and suggests that they just be shaved as best as they can; but he must go or else the quest would not be successful, although Sancho admits that he has never heard of knights who were unable to complete adventures without their squires.
While Clavileño, the flying wooden horse, is carried in and set before knight and squire, La Trifaldi informs them that they must be blindfolded during the trip through the sky; and after more protesting, Sancho agrees to be blindfolded and hangs on to Quixote for the imaginary flight. The duke and duchess spared no props to create wind and heat and an explosive landing, and when the ride is over, Quixote and Sancho learn that the deed is complete: Malambruno is content, duennas are smooth and beardless, and Clavijo and Antonomasia have been restored to their natural state. Now, once the whipping is complete, Dulcinea will be free.
The next day, the duke advises Sancho to prepare for his promised governorship, which is another jest to be played by the duke, duchess, their servants, and retainers. But beforehand, Don Quixote gives his squire plenty of prudent counsel including: how to be a fair judge, be compassionate and virtuous, and show pity and clemency.
Continuing in wise counsel: be deliberate, avoid eructation, which is a refined way of saying belching, dress properly dress, eat minimally, wake early, and avoid the never-ending proverbs, whereas Quixote complained that Sancho was “choking him with his string of proverbs.” Nonetheless, the candid squire tells his master that he would rather go to heaven as plain Sancho than to hell as governor Sancho, which pleases his master; hence Quixote adds that Sancho’s “good disposition proves him worthy to govern a thousand islands.”
