What is love?
Look into the eyes of an innocent child and see, that is love!
Come back home to your pet dog, see how it wags its tail and jumps all over you, that is love!
And when you have fallen in love with someone and you are remembering them, look at your face in the mirror and see! You will find the same love in your own eyes. Love is such that it makes even a stone melt.
Just like how our body is made of amino acids, carbohydrates, proteins, vitamins; our consciousness is made of love and beauty.
