Constant.

Referring to it all of the time we fear its character.
Its passing defines us drawing our very appearance.
Reflection upon its demands can govern our nature.
A lasting presence informs us of its true significance !
...........................................
Recording everything that happens within its realm,
We acknowledge it has a complete hold on our lives !
We cannot affect a capability to give or overwhelm.
None escape its dominance as it continually thrives !
...........................................
Its stature is more than we can sometimes cope with.
Its perceived fleeting manner is where its power lies.
It has been around far longer than our homely Earth !
Before a majesty everyone bows and in the end dies !
