In Buddhist mythology, the concept of rebirth illustrates the cycle of life, death, and renewal, known as samsara. It reflects the belief that actions (karma) in one life influence the circumstances of future lives. This notion serves to encourage ethical behavior and awareness, as individuals are taught that their choices have enduring consequences. The cycle of rebirth also underscores the aspiration for nirvana, a state of liberation from suffering and the endless cycle, guiding practitioners toward spiritual enlightenment and ultimate peace.
