Thomas Merton

Quote (seen on an episode of the tv show Criminal Minds):
“Love is our true destiny. We do not find the meaning of life by ourselves alone--we find it with another.”

And, while searching for the correct wording of the above quote, another popped up: 
“Love seeks one thing only: the good of the one loved. It leaves all the other secondary effects to take care of themselves. Love, therefore, is its own reward.”
