The Knight’s armor was originally designed for protection and status. However, the tragedy begins when he refuses to take it off even to sleep or eat. Fisher uses the armor as a metaphor for the defenses we develop—cynicism, stoicism, or performative virtue—to shield ourselves from vulnerability. The paradox is clear: the more we protect our "image," the less we are able to feel the warmth of a real human connection. The rust is not a sign of age, but of neglect of the inner self.

This book is a masterpiece of the Spanish language. However, many OCR (Optical Character Recognition) scans butcher the text. You might find strange characters replacing accents (like ? instead of ¿ ). A good EPUB repack ensures that the Spanish orthography is perfect, allowing you to focus on the wisdom of the words rather than typos.
