Love is the best gift of life, without love life is like body without soul. Every emotion, every feeling, every relationship is only due to love. Even the feeling of hate is also due to love, as the feeling of hate comes when the quantity of love is less comparatively . one can rule over the whole universe by love only. When a heart has a feeling of pure love then only it can connect to god because god has only love in his heart, there is no space of other feelings, it is also written in our Vedas that one can find or reach the god only if he loves the creation of god. There is no proof in our history that anybody had reach to god by anger or hate or power.
Scientifically it also has been proved that a heart full of love or having a feeling of love is more healthy then other.
So one should always spread love to make our life and universe beautiful. Love is of many kind viz. Parents-child love, brother-sisters love, friends love, husband-wife’s love etc.... but the result is only one i.e. happiness, peace and harmony.
