I know of only one duty, and that is to love.

Albert Camus

A coward is incapable of exhibiting love; it is the prerogative of the brave.

Mahatma Gandhi

Love doesn't just sit there, like a stone, it has to be made, like bread; remade all the time, made new.

Ursula K. Le Guin, The Lathe of Heaven

Darkness cannot drive out darkness; only light can do that. Hate cannot drive out hate; only love can do that.

Martin Luther King Jr.

I love you right up to the moon — and back.

Sam McBratney

I seem to have loved you in numberless forms, numberless times, in life after life, in age after age forever.

Rabindranath Tagore
