In this excerpt from "The Chronicles of Narnia," Aslan reflects on the nature of desires and the consequences of obtaining them. He acknowledges that desires can lead to fulfillment, giving one the appearance of strength and longevity, but warns that such gains can come from a corrupted heart. This contrast emphasizes that merely obtaining what one wants doesn't guarantee happiness or satisfaction.

Aslan's words suggest a deeper truth about the human experience: even when people achieve their deepest wishes, they may find themselves unhappy or discontented. He highlights the importance of the heart's nature in shaping the experience of one's desires. Ultimately, the pursuit of one's aspirations must align with goodness, or the resulting fulfillment may transform into misery.
