All we need is love - but what does that mean?

I'm watching these TV shows called OZ. They are about maximum security prison in the USA and scary to mention as well.. but what I find extremely interesting is the part of the narrator in the show.
He's part of the prison inmates but his major role is to, in my opinion, to challenge and give food for thoughts. How intereting! in a prison tv show!

One of the toughts they were provocing is using the saying "head over heels" when talking about love. This saying, originally, comes from old Britain when people committed a crime of some sort they were hung upside down, with their heels over their head. from there on out it was used when you were in a position of no control, in state of helplessness. so why use that phrase when it comes to being in love?
- their comment was; being in love IS like being helpless, being out of control. Sometimes in a good way and sometimes in a negative way. It was quite interesting to hear this.

And it all came together when I watched a movie called The holiday. One part of that movie, one of the main character is talking about being in love. Some people are in love with each other but many ( unfortunately ) are in love without having that love being reciprocated. It's painful, you feel helpless and out of control of your own emotions.
No one ever talks about these people, these unlucky ones that go through being "head over heels" literally speaking in love.

so I have to wonder, if explanations are taken from painful experiences to showcase what love is, or what it means to be in love - is love then partly negative?
My experience of love is both negative AND positive. And most of the time it's been a painful process of helplessness and doubt.
But there are experiences of joy, satisfaction, strength and peacefulness in there as well.

Love, as a topic for discussion, is extremely interesting. People have different views on what it means and how to show love. All we can agree on is twofolded; that it is hard, to either be in love alone or with someone, even if the end result of this hardness is good or bad. and that we all disagree on what love actually means!

- with love -
