"Love alone is the only reasonable activity or pursuit of humankind. Like a key made for this one lock alone, we find in our own soul a feeling that gives us what it is we yearn for. And this feeling not only solves the riddles of life, but finds in them the very possibility of happiness. For love not only annihilates our fear of meaninglessness but empowers us to seek the happiness of others. And this indeed is our greatest happiness." -- Leo Tolstoy
