The Two Inside

Free style poem to an image prompt contest

They are two
Together, but apart
Touching, never uniting

They are one
Existing in one space
Yet a chasm apart

Like Yin and Yang
The light of day
And the darkness of night

Like Id and Super Ego
Touching the soul
But parted by Ego between

Which am I?
Am I burning desire?
Or caution, and control?

Can I be
Both child of light
And pawn of darkness?

If they came together
Would both extinguish?
Would one prevail?

Perhaps it’s best
They touch and know
That the other is there

But never meet 
And fully embrace
Across that divide
