What is love?

ok.
so gunner wanted to know what we thought love was.
So I went and found some quotes that i thought were pretty nice.
and here they are...

"Love is everything it's cracked up to be. That's why people are so cynical about it...It really is worth fighting for, risking everything for. And the trouble is, if you don't risk everything, you risk even more."

"Loves makes your soul crawl out from its hiding place."

"To love is to receive a glimpse of heaven."

"Love is like a violin. The music may stop now and then, but the strings remain forever."

"Love doesn't make the world go round, love is what makes the ride worthwhile."

"Love is like quicksilver in the hand. Leave the fingers open and it stays. Clutch it, and it darts away."

i love this one :

"Love is friendship set on fire."

This last one is kind of confusing, but I liked it.

"To love is to suffer. To avoid suffering one must not love. But then one suffers from not loving. Therefore to love is to suffer, not to love is to suffer. To suffer is to suffer. To be happy is to love. To be happy then is to suffer. But suffering makes one unhappy. Therefore, to be unhappy one must love, or love to suffer, or suffer from too much happiness."

so basically summing up what i think love is:
unconditional
incredible
so powerful it makes your heart ache

it involves
suffering
crying
fighting
doing things that you might not necessarily do otherwise

but in the end,
love REALLY is what keeps our human existence going
it's the base of everything we know

so yeah...
that's all i got
what about you gunner?
