Jealousy-at least as far as he understood it from his dream-was the most hopeless prison in the world. Jealousy was not a place he was forced into by someone else, but a jail in which the inmate entered voluntarily, locked the door, and threw away the key. And not another soul in the world knew he was locked inside. Of course if he wanted to escape he could do so. The prison, was after all, his own heart. But he couldn't make that decision. His heart was as hard as a stone wall. This was the very essence of jealousy.
In Haruki Murakami's "Colorless Tsukuru Tazaki and His Years of Pilgrimage," the protagonist reflects on jealousy as a self-imposed prison. This prison is not constructed by external forces but rather by one’s own emotions and choices. The individual willingly enters this confining space, sealing off any chance of escape, and strangely, no one else is aware of this internal struggle. This metaphor highlights the profound isolation jealousy brings upon a person, as it is a private torment that others cannot see.
The essence of jealousy manifests as an emotional barrier, making it difficult for the individual to break free. The heart becomes hardened, echoing the sentiment that while the prisoner can leave at any time, they remain trapped due to their own inability to let go. This powerful imagery captures the anguish of jealousy, illustrating how it transforms a person’s emotional landscape into something unyielding and impenetrable, thus reinforcing the theme of self-entrapment.
