In this passage from "The Golden Compass," Lyra reflects on her past, considering it as something she has moved beyond. She acknowledges that her previous experiences are no longer relevant to her current journey. This detachment signifies her growth and transformation as she embarks on a new adventure.

As Lyra ascends to new heights, both physically and metaphorically, she experiences a profound sense of isolation. The unusual light surrounding her enhances this feeling, suggesting that she is stepping into a world that is unfamiliar and extraordinary. Her focus and determination indicate that she is fully immersed in her exploration, leaving the past firmly behind.
