Nothing

Tell me something. Or tell me rather- nothing.

Good luck with that one.

Nothing isn't exactly the easiest concept to grab hold of- simply because there really isn't much to grab onto in the first place.

Then again, that should make it that much easier to grasp. Think, just think about it. Nothing, the idea of emptiness, purity... nothing. Not much to think about now is it?

Think again. Or don't- the  simple act of thinking of nothing itself is in itself thinking of something- in this sense nothing. A bit of a loophole.
