Well, what is love? To me, love is, essentially, a strong undeniable feeling that an individual holds inside of them.

While Shaw's definition is a good one, I think that one of the interestings thing about love is that it is not held within us, but rather draws us out of ourselves. As Freud (my guy) points out:

At the height of being in love the boundary between ego and object threatens to melt away. Against all the evidence of his senses, a man who is in love declares that 'I' and 'you' are one, and is prepared to behave as if it were a fact. (Civilization and its Discontents p 13).

Love, at its best, draws us out of our little ego-shell. Love for another pulls us out of ourselves, and, hopefully eventually draws us into a more universal concern for our fellows. I don't mean to be all Pollyanna Sunshine here, but its been my experience that love, as a workable lifestyle, is a constant experiment in living outside ourselves. The neccesary daily altruism lovers experience (when things are done in each other's best interest, not for one's individual needs and wants) brings about a transformation of self, so that over time a specific love for a specific person can transform into an overall general love (especially if you're Morman. Kidding).
