The realisation of one's own death is the point at which one becomes adult.
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.
