He did not miss anything but looking for a lady from whom to fall in love; Because the walking knight without love was tree without leaves and without fruit and body without soul.
In "Don Quixote," the protagonist is portrayed as a knight whose quest for love is essential to his identity and purpose. He embarks on various adventures, motivated by a desire to find a lady and experience the transformative power of love. Without this emotional connection, he feels incomplete, much like a tree stripped of its leaves and fruit or a body lacking a soul.
This metaphor highlights the deep yearning for love that defines human existence. For the knight, the search for a beloved is not merely an act of romance but a fundamental aspect of being alive. Love enriches his journey, bringing meaning to his life and adventures, and without it, he feels barren and aimless.
