Love is great, it's the unifying "force", it's why holds us together, instead of having a dog-eat-dog world where everyone is out for themselves. It's actually necessary for people to be fulfilled, to share and express love with each other, to some degree in some way on some level.
Love may be a fundamental, if not the most fundamental, "thing" in the universe.
Love can be very deep in some people's and spirit's cases and perform miracles for others who are in desperate situations. Perhaps some people or spirits have so much love in them that they devote their lives to becoming better at saving certain types of people or spirits.
Conversations with God book 3 has some interesting things to say about love.
"Now in the human reality, you will find that you always seek to love, and to be loved. You will find that you will always yearn for that love to be unlimited. And you will find that you will always wish you could be free to express it.
You will seek freedom, unlimitedness, and eternality in every experience of love. You may not always get it, but that is what you will seek. You will seek this because this is what love is, and at some deep place you know that, because you are love, and through the expression of love you are seeking to know and to experience Who and What You Are.
You are life expressing life, love expressing love, God expressing God.
All these words are therefore synonymous. Think of them as the same thing:
God
Life
Love
Unlimited
Eternal
Free
Anything which is not one of these things is not any of these things.
You are all of those things, and you will seek to experience yourself as all of these things sooner or later.�
As for romantic love, I think that people have this societal bias that says that romantic love between two partners should last forever, at least when it's serious enough to get married. That's why people "tie the knot" and include in their vows "til death do us part." But in reality, though life-long relationships work for some people, the only constant is change. I think it's completely natural and more common for a love interest to take its course and then fizzle out. (Though, at least in this culture, they generally don't fizzle out--they end in mutual contempt, which shows that there's something fundamentally wrong with our approach to love.)
For this reason I don't believe in marriage.
Also, I don't agree with the social norm that love has to be monogamous, even serially. I don't agree with the idea of "cheating" either. It's all about fear, ego and control. You restrict your partner's freedom to romantically love or otherwise sexually enjoy whomever else they wish because you want them all to yourself, or you fear losing them. And also just because you're taught by society that it's how things are supposed to be. Love should be unrestricted, not mutually restricted to quell each other's fears. Though within current society and culture / common psychology / levels of maturity I think that trying to pull off polyamorous relationships can be tricky or problematic.
Another important thing about what we call love is that we often think we "love" a person when, really, that person just has traits that we desire. In one of Neale's books, he says that people often say "I love you very much" when they really mean "I trade you very much." Perhaps this comprises the difference between "infatuation" and love.
Also important--and this is related to a couple of the other subjects above--is that we approach romantic love in a very need-based way. We need things from the other person, as opposed to just wanting to give to them because we love them. I think this is the main cause of all breakups. What people are prepared to give and what we think we "need" from them often don't match up. I think people should try to steer away from entering into relationships with a need-based approach.
That's all I can think of about love.
