“You know when love's
shining in your eyes
it may be the stars
fallen from above.
And you know love
is with you when you rise,
for night and day belong to love.”

1950s, Loving Your Enemies (November 1957)
Context: The Greek language comes out with another word for love. It is the word agape. …agape is something of the understanding, creative, redemptive goodwill for all men. It is a love that seeks nothing in return. It is an overflowing love; it’s what theologians would call the love of God working in the lives of men. And when you rise to love on this level, you begin to love men, not because they are likeable, but because God loves them. You look at every man, and you love him because you know God loves him. And he might be the worst person you’ve ever seen. And this is what Jesus means, I think, in this very passage when he says, "Love your enemy." And it’s significant that he does not say, "Like your enemy." Like is a sentimental something, an affectionate something. There are a lot of people that I find it difficult to like. I don’t like what they do to me. I don’t like what they say about me and other people. I don’t like their attitudes. I don’t like some of the things they’re doing. I don’t like them. But Jesus says love them. And love is greater than like. Love is understanding, redemptive goodwill for all men, so that you love everybody, because God loves them. You refuse to do anything that will defeat an individual, because you have agape in your soul. And here you come to the point that you love the individual who does the evil deed, while hating the deed that the person does. This is what Jesus means when he says, "Love your enemy." This is the way to do it. When the opportunity presents itself when you can defeat your enemy, you must not do it.

Context: We know only fragmentarily this extraordinary thing called life; we have never looked at sorrow, except through the screen of escapes; we have never seen the beauty, the immensity of death, and we know it only through fear and sadness. There can be understanding of life, and of the significance and beauty of death, only when the mind on the instant perceives “what is”. You know, sirs, although we differentiate them, love, death, and sorrow are all the same; because, surely, love, death, and sorrow are the unknowable. The moment you know love, you have ceased to love. Love is beyond time; it has no beginning and no end, whereas knowledge has; and when you say, “I know what love is”, you don’t. You know only a sensation, a stimulus. You know the reaction to love, but that reaction is not love. In the same way, you don’t know what death is. You know only the reactions to death, and you will discover the full depth and significance of death only when the reactions have ceased.
