What isn't love?

What is and what isn't love?

Love is powerful
Love is feirce
To the heart it belongs
Through the heart it can peirce

Love is large
You're never prepared
Nobody's in charge
..Love isn't Shared

Love is pain
Love is despair
Tears like rain
..Love isn't fair

Love is amazing
Love is awful
Love is heartbreaking
..Love isn't lawful

What isn't love?
..What is?
Some say it's a gift from above
I say it's a gift from within
