What is LOVE?

Reading from one of my favourite tweet on LOVE,
I asked myself what is LOVE?
reading down the line I have an explicit answer.
Love never gives up. Love cares more for others than for self.
Love doesn't want what it doesn't have. Love doesn't strut,
Doesn't have a swelled head, Doesn't force itself on others,
Isn't always "me first," Doesn't fly off the handle,
Doesn't keep score of the sins of others,
Doesn't revel when others grovel, Takes pleasure in the
flowering of truth, Puts up with anything, Trusts God always,
Always looks for the best, Never looks back, But keeps going to the end.
Love never dies.
Hmmm... therefore emotion/feelings is not Love, though it could be a sort of measurement in it.
Emotion is a thermometer, a barometer, a fuel and a medium of expression of feelings
We cannot confuse the thermometer with temperature, and if thermometer is not temperature, emotion cannot be LOVE
