I think love is not something anybody can define.
Its been such a long time that poets, philosophers, artists, musicians etc are all trying to explain what love is, but there is no accurate defination yet and I don't think there will ever be. Love can't be defined by words, it can only be felt by hearts. People often ask themselves "How do I know when I am in love?" , you know you are in love the moment you cant explain, not only others but yourself why you feel what you feel around them. Love will leave you speechless.
(Just abstract thoughts)
