What is love?

What is love?
Is it a feeling that encompasses all human emotions,
Is it just a feeling,
that blinds intelligence.
Is it a craving for lust,
that corrupts a person.
Is it a stepping stone,
that leads you to success.
or is it just a desire
to have a beautifull girl by your side,
So that you can show off, and
use her to reap selfish benefits.
Is it a divine relationship
where two souls truly understand each other,
respect each other's feelings,
live for each other, and
become one by body and soul.
If this ain't love,
then what is it?
