If you find a neighbor in need, you're responsible for serving that neighbor in need, you're responsible for loving a neighbor just like you'd like to love yourself.
Love, what is love? I don't think you can really put it into words. Love is understanding someone, caring for him, sharing his joys and sorrows. This eventually includes physical love. You've shared something, given something away and received something in return, whether or not you're married, whether or not you have a baby. Losing your virtue doesn't matter, as long as you know that for as long as you live you'll have someone at your side who understands you, and who doesn't have to be shared with anyone else!
I am grateful to have been loved and to be loved now and to be able to love, because that liberates. Love liberates. It doesn't just hold - that's ego. Love liberates. It doesn't bind. Love says, 'I love you. I love you if you're in China. I love you if you're across town. I love you if you're in Harlem. I love you. I would like to be near you. I'd like to have your arms around me. I'd like to hear your voice in my ear. But that's not possible now, so I love you. Go.'
You, methinks you think you love me well;
For me, I love you somewhat; rest: and Love
Should have some rest and pleasure in himself,
Not ever be too curious for a boon,
Too prurient for a proof against the grain
Of him ye say ye love: but Fame with men,
Being but ampler means to serve mankind,
Should have small rest or pleasure in herself,
But work as vassal to the larger love,
That dwarfs the petty love of one to one.
