This is my take on love, I hope it makes sense. To me love seems to be a feeling, and like someone said above, a way to live, I guess it's many things, the divine language.
I had fallen in love with someone about 15 years ago, when I was in high school, but looking back, it wasn't what I would consider love now. When I started having these experiences, I started feeling what rumi talks about, a unity with the universe, a burning fire which is literally in the heart, to me this feeling is love, although I'm vastly over simplifying it. Another thing that showed me real love is meeting a very special person. The love I feel for this person is totally different than anything I've felt for anyone else, it's overwealming at times, and just like the burning fire that the Sufis talk about, this feeling is literally a burning in my heart, not butterflies in my stomach like my first love. It's a totally selfless sort of thing, she was the first person I had ever met who fully accepted everything about me, with no judgment whatsoever. And sometimes I'm a mess because of all this lol, but I'm sure everything will work out just as it should. When it comes to love for another person, I think real love is love without ownership, never having to explain yourself and total acceptance of the one you love. In other words, I think real love also has no expectations, or tries not to anyway, it makes life so much easier. if you have to put on an act, it's not real love.
Love is the feeling one has for their child, that a child has for its mother. Love is empathy, love is understanding. Love is random acts of kindness, love is life itself, for some anyway.
Love is a lot of things I guess. Love is everything in a way.
