Brain The Riddle

I am complex

So I rummage apex.

I can create

But I can also incapacitate.

The way you incite me

Is the way you look at me.

Coercive subconscious of commoners

Where harmony matters.

And no clutter

When rampant whits of grey glitter;

Their pensive faces glare!

The hemispheres differ

As the persons differ.

Just like the white angel

The hemispheres try to mingle

But end in ‘shingle’.

Above all I am the riddle!
