What is the essence of love?


What is the essence of love? Are there any other forms of love existing besides physical love? Can love be eternal? 

To begin with, Love is an abstract noun which means for some it is a word unattached to anything real or sensible, that is all; for others, it is a means by which our being – our self and its world – are irrevocably affected once we are ‘touched by love’; some have sought to analyze it, others have preferred to leave it in the realm of the ineffable. Yet it is undeniable that love plays an enormous and unavoidable role in our several cultures; it is discussed in song, film, and novels – humorously or seriously; it is a constant theme of maturing life and a vibrant theme for youth.
