What it is Love ? A subtle blindless feeling that push oneself into physical or spirit attraction for another human being mainly based our own mental expectations and desires. A powerful energy that makes oneself better far beyond one's own ability to deal with events and social situations, linked to what it is supposed to be right. A concret or subtle act that motivates us to deal with our closed friends and family when they need some presence or some help. Love is also the second brain of the body that manages all human organs : the Heart with its powerful energy. May be Love is all of this, or just a marketing thing.
Loving someone is not saying yes to everything the person needs, that is slavery or mental submission.
Loving someone is first, acting according our own freewill and freedom, then, it is to put oneself in the situation of the person we are currently encounter, finally is acting using our own discernment to make things better or trying to at least. Do not forget the two rules. Indeed, Love is supposed to make us stronger, not to low our energy and vibrations, because it won't be love, but vampirizing. Love is sharing, like the tibetan saying "a candle can sharing its own flame to a million candles without dwindling its one flame". That is Love. Like the Into The Wild movie, from the book of the same title " Happiness is real only when it's shared". Happiness is (a) cloth(es) of love. One's does not have to feel happy if one's lives with Love inside.
We may say Love is : how to make things fair.
"Cowardice asks the question Is it safe ?
Expediency asks the question Is it politic ?
Vanity asks the question Is it popular ?
But conscience asks the question Is it right ?
And there comes a time when one must take a position that is neither safe, nor politic, nor popular;
but one must take it BECAUSE it is right."
Martin Luther King, Jr.
