If you don't have it, no matter what else there is, it's not enough.Love, like truth and beauty, is concrete. Love is not fundamentally a sweet feeling; not, at heart, a matter of sentiment, attachment, or being "drawn toward." Love is active, effective, a matter of making reciprocal and mutually beneficial relation with one's friends and enemies.it's a human need. spread the love.
