The Four Seasons
First, it starts like infant's first scream,
Spring is the season of birth
Then, it grows as though in a dream.
Plants, animals grow throughout the summer
Next, it dims as the end draws near,
In the fall, trees lose their leaves and animals prepare for winter by stocking up for hibernation or migrating
Last, it ends as gone's all that's dear.
In the winter, animals are hibernating or have left and plants are covered in snow
Then, anew recurs its first breath,
Endless cycles of life and death.
There were 4 steps in it's cycle, in the winter animals/plants die, and the cycle starts over with life in the spring
With each turn, all creatures obey,
The cycle that holds, the greatest of sway.
All the creatures follow the seasons
