What is love?

a voice enchoing in my mind... a voice came with the question pointed toward me.. a question asked me "what is love to you?". I responded to the question with answer "The pain you suffered without presense of special person around you. That's love" .

It was just impulsive answer straight out from my heart without filtering through my brain. I don't have any explanation to that answer. If search through google, who has definite answer?i guess not.

If you guy has d answer. Tell me about that...
