A Rippel in Life

A repeat of one symbol
For what is it representable?
A tear from joy, from sorrow
A sign of yesterday's tomorrw
Carved into the entrails of a tree
Or a rain drop falling free
From the grasps of clouds
The invisible roaring of sounds
Surrounding the world one sign
Who came up with this design?

*Note* I know this is rough. I wrote it for a friend who saw me making notes on how repeats itself. Hope you like it though!
