In this reflection, Lyra expresses her profound realization about life and the passage of time. While she was away, her focus was solely on the present moment, as she grappled with the uncertainty surrounding her future. The weight of not knowing what lies ahead made her feel as if her life were limited and predefined, leading her to spend her time immersed in what's immediately before her.
Now, with the discovery that she has an entire future to explore, Lyra feels both exhilarated and overwhelmed. This new opportunity brings a sense of confusion, akin to having an alethiometer—an important tool—but lacking the understanding to interpret its meaning. This metaphor highlights her struggle to navigate her newfound potential and the complexities of life that lay before her.
