The Eternal Return is basically the theory that there is infinite time and a finite number of events, and eventually the events will recur again and again infinitely. Consider the world as a super-complex chess game. If games of chess are played one after another forever, eventually a game will be repeated since there is only a finite number of possible games. It is the same with the world; eventually events will recur in the same order. The world is an eternal process of coming to be and passing away. The process, however, has no beginning or end. Eventually every combination of matter and energy will be realized and repeated an infinite number of times.
