Analysis of Stars.

You think you can define me,
That I'm a tick in just one box,
Like my being is a door,
That a single key unlocks,
But let me tell you something,
I have the universe inside,
I hold an untamed ocean,
With a constant changing tide,
I'm home to endless mountains,
With tips that touch the sky,
Flocks of grand migrating birds,
And deserts harsh and dry,
I house the wildest rivers,
And a host of sweeping plains,
I feel in waves of sunshine,
Or in unrelenting rains,
Don't tell me that you know me,
That "this right here is what you are",
I am the universe in motion,
For I was born from stars.
