What is life?

To live is to make something out of nothing, to create something and to exist. Life is a time limit and a process. Life is a limited existence, and it is a process from scratch to nothing. Life is only a lifetime, and vegetation is only an autumn. Life begins with nothingness and ends in emptiness. You've never been here. You have to go somewhere else. Between this emptiness and this coming and going, life is a great and beautiful existence. This will to live is vitality, and this is vitality. It's flower of life, a miracle of the universe. Because life is innate, life is only limited by time, so the only chance for life to continue to exist is endless creation-creating new life and creating the continuation of life.
