The problem nowadays is that love is interpreted on a gross level. Just as many people are attracted to the size and glitter of a fake diamond, so are they swayed by false, superficial love. There is no value in either. A real diamond is often quite small, but it is flawless. That is where its value lies. Real love is like a tiny diamond: it is not flashy and it is without a single flaw.
Real love is one hundred percent pure. There is nothing artificial mixed into it. It is clean. There are no ulterior motives in real love.
