The quote reflects on the ephemeral nature of existence, suggesting that life and desires are insubstantial, much like shadows. The imagery of phantoms and clouds emphasizes the fleeting quality of human experiences, with routine and time moving forward as if carried by a train. In this contemplation of life’s transience, the narrator acknowledges the inevitability of passing days and the superficiality of many worldly pursuits, underpinning a sense of resignation.

It is portrayed as the core purpose in life, eclipsing all else and hinting at a deep, shared connection with a past love that transcends even death. This concluding thought elevates the concept of love to an eternal status, grounding the narrative in a bittersweet context of remembrance and loss.
