The concept of rebirth has always provided humanity with a sense of a new life and hope. Whether it is the idea of life after death, or the idea of the metaphorical rebirth from sin to purity, the idea of being reborn still provides much inspiration and motivation to us.
Even in everyday life, the old dies out and becomes new again. We fall into a state of unconsciousness every night, and become aware once again of the world around us in the morning.
Life kills our souls quite often. We fall into states of despair, hopelessness, sadness, sorrow, and depression at various stages in our lives.
Those are stages in life in which we must look into ourselves, let our old, tired, and feeble souls perish away, and bring life to a new self-realization that, so long as we can still breathe, there still is hope.
