In Miguel de Cervantes Saavedra's "Don Quixote," the phrase "Better in hand is better flying" suggests that having something tangible or certain is more valuable than pursuing idealistic or uncertain pursuits. This quote emphasizes the importance of practicality and the wisdom in appreciating what one already possesses, rather than chasing after dreams that may never materialize.

This sentiment reflects the overarching themes in "Don Quixote," where the protagonist embarks on misguided adventures while often overlooking the significance of reality. The message encourages readers to recognize and value the security of their current situation over the allure of unattainable aspirations.
