Everything in our universe happens in a cyclic manner. A short cycle: we inhale, exhale, and inhale again. An average human breath about 21600 times a day.
We are born, live and die, and re-born, which is a longer cycle. The longest cycle is the birth, existence, and dissolution of our universe. Ancient scriptures tell us that the length of this cycle is a colossal 4.2 billion years. The long-living universe exists passing four Yugas.
