The quote by Lawrence Durrell suggests that understanding and accepting the reality of one's own death is a key moment in reaching adulthood. It implies that maturity involves a conscious awareness of mortality and the transient nature of life, which leads to a deeper sense of responsibility and self-awareness.

This realization serves as a pivotal point that shapes how individuals perceive their existence and make meaningful choices. Recognizing mortality can foster a sense of urgency, wisdom, and a more profound appreciation for life, marking a transition from innocence to mature understanding.
