Love

There is an extremely powerful force for which science has so far found no formal explanation. It is a force that includes and governs all others and is even behind any phenomenon that operates in the universe and has not yet been identified by us. This universal force is LOVE. Love is Light, since it illuminates those who give it and receive it. Love is gravity because it makes some people feel attracted to others. Love is power, because it multiplies the best we have, and allows humanity not to become extinct in its blind selfishness. This force explains everything and gives meaning in capital letters to life. This is the variable that we have ignored for too long, perhaps because love scares us, since it is the only energy in the universe that human beings have not learned to manage as they wish. When we learn to give and receive this universal energy, dear Lieserl, we will see that love conquers everything, transcends everything, and can do everything, because love is the quintessence of life.
