In this passage, the essence of life is portrayed as fleeting and limited. The author reflects on how brief moments of clarity and understanding illuminate our existence, suggesting that we often fail to grasp the significance of these revelations. Once these moments pass, they may never return, leaving individuals to navigate a life filled with regret and a profound sense of loneliness.

The imagery of a "withered corpse of what should have been" evokes a strong sense of loss. It highlights the emotional toll of missed opportunities and the weight of regrets that anchor us in a twilight state, devoid of hope. This reinforces the idea that recognizing and appreciating life's transient moments is crucial, as failure to do so can lead to a life mired in sorrow and unfulfilled potential.
