Because the walking knight without love was tree without leaves and without fruit and body without soul.
The quote from "Don Quixote" by Miguel de Cervantes highlights the deep sense of emptiness and lack of fulfillment experienced by a knight who does not possess love. It draws a poignant comparison between a knight devoid of love and a lifeless tree that bears no leaves or fruit, emphasizing that love is essential for a complete and vibrant existence.
This metaphor suggests that just as a tree requires its leaves and fruit to thrive and contribute to the ecosystem, a person's existence lacks purpose and vitality without love. The imagery of a body without a soul further reinforces the idea that love is fundamental to one's identity and essence, indicating that an unloving life is akin to a soulless existence.
