Poetry is the key to the soul.
It cracks it open like a tin can, and most times, it floods it with a waterfall of tears.

Poetry is the key to the mind.
It enters and cleanses any impure part, forcing the mind to realise it's wrongs and inspire it to do right.

Poetry is the key to the heart.
It enters the heart and sweeps away residue from heartbreak and repairs any cracks to be perfect once again.

Poetry is the key to feelings.
It enters the heart and soul and pierces your emotions like a sword through another's heart, making you realise that he's not the one and that he's doing this all for fun.

Poetry can enter pretty much anything.
