Understanding Vocabulary in Context

In the following passage, a poet reflects on the passage of time and its effects on memory:

"As shadows lengthen and daylight fades, I often find myself caught in the quagmire of reminiscence, where the past seems both vivid and elusive. Each recollection is a palimpsest, layered over with the dust of years gone by, yet somehow lucid enough to evoke a smile or a tear. Time, relentless in its march, reshapes my thoughts, imbuing them with a resonance that is as poignant as the sweetest melody. In this delicate balance, I cherish the moments that linger, unwavering in their beauty despite the all-consuming passage of days."
