Everything around you, time, space, the universe, life, and death needs a cycle to exist. Without cycle, there will be not any kind of existence.
Look around you more attentive and you will see the cycle. Moons revolve around their planets. The planets revolve around their suns, and the suns revolve around the center of their galaxies. At the same time, all of them rotate around an axis. Do you know how old Milky Way is based on its own rotation? Very young. Whatever.
Likewise, in outer space, life on the planet needs many cycles to exist. Everything on the earth cycling to maintain life. The quick is dying and their remains will become material for the newborns. Likewise almost all elements, the water cycles from one form to another.
Letâs take a look at human societies, those who claim they are superior to nature. All political, economical, and cultural systems/regimes are based on a cycle. It doesnât matter which system they brought until today, only its facade changed and the fools are hated each other for it and even fought for it! But forget about those complicated things. Letâs go basic and take a closer look at your daily life.
What are you doing in your daily life? In a week? In a month? You repeat the same actions over and over again to maintain your existence. And this is your cycle. There is no escape from it if you want to exists. You can escape from a cycle but in short time you will find another one. You love it, you worship it. It is your God. But do you know the most fun fact about it? You are doing it unconsciously, with an instinct. There is no complex philosophy, education, or brain in it. Likewise Anduin, you are dominated by it!
Every single day you go to work/school again, you keep revolving around your job/boss/studies by repeating the same actions again. You eat again, you drink again, you login WoW again, and you do your daily actions in the game again. You ran the same dungeon again. You encounter a priest again, you do the same quest again.
You know your class rotation, if you are not good at it, you are facing problems again and keep pressing the same skills again. Again, again and again.
This is the cycle that Sylvanas mentioned. She was very angry about that cycle.
Are you understanding now? Have you ever heard the term Ouroboros? It is carved on the stones in Oribos.
