Love is an integral virtue i.e. love is essential for completeness of every human life/society. Oh! Yes, anyone that lacks love is incomplete & can't make positive impact in the lives of people around him/afar off. ~Emeasoba George.
Love is life. All, everything that I understand, I understand only because I love. Everything is, everything exists, only because I love. Everything is united by it alone. Love is God, and to die means that I, a particle of love, shall return to the general and eternal source.
