The ancient mythology of the Druids explains the transition from life to death as a cyclical and natural process. They believed in the reality of the afterlife and the notion of rebirth, where souls transition to different planes of existence. Myths associated with this belief system often reflect the veneration for ancestors and the interconnectedness of all life. These narratives promote a respect for the natural world and encourage understanding life's impermanence, highlighting the belief that death is not an end but a transformation into another state of being.
