Each event could either take part having a certain shape, having its own cycle, repeating itself after time, or could either be part of another superior event that has its own cycle.

Events like daily routine, or the changing of the seasons, or the shifting of the planet's Poles, or even the world itself are all cyclic events. Symbolic, all events occur on the shape of a circle, two opposites intertwining, just like a snake, biting its own tail.
The cycles actually represent a Balance either between the consumption of energy and it’s (re)generation, either between different evolutionary steps.
In the Principle Hierarchy, this Principle reigns over others, but is also inferior to some, making it very difficult to precisely reveal its importance. It exists in absolutely in every event that could have an opposite, for its role is that of creating and maintaining the Balance. Due to its repetitive nature, it can cover very long periods of time, or can even part from existence, due to the fact that the Principle can apply to that too, for even existence has an opposite, even if it is abstract and hard to understand.
