I read something like this in Chinese:
A conversation between a man and Buddah about affair:
M: Dear buddah, I am a married man, but I am deeply in love with OW, I don't know wht to do.
B: Can you be sure that this OW you love now is the last ONLY woman in your life?
M: Yes.
B: Then divorce, and marry her.
M: But my wife is kind, gentle and nice. Arn't I a bit cruel and imoral to do that?
B: A loveless marriage is cruel and imoral. You already love someone else, but her. It is right to D.
M: But my wife loves me, really loves me.
B: She is happy.
M: I will D her and marry OW, she should be painful. How can she be of happy?
B: In your M, she has love for you, but you already lose the love for her because you love OW. Having is happy, losing is painful. It is you who is painful.
M: But I will D her and M OW. So she is losing me, she should be the one who is paiful.
B: You are wrong. You were just an subject of her true love in the M. When this subject does not exist anymore, her true love will extend to another subject, because she never lose her true love in her M. So she is happy and you are painful.
M: But she said that she only loved me in her life, never anyone else.
B: Did you say that too?
M: Me, me, me,...
B: Look into the three candels in front of me, which is the brightest?
M: I can't tell, it seems that they are all bright.
B: These three candles are like three women, one of them is the OW you love now. There are so many women in the world, you even cannot tell which candel is the brightest, how can you be sure OW is the last ONLY women in your life?
M: I, I, I, ...
B: Now take a candle close to you, use your heart to see which one is the brightest.
M: Of course, it is the one in front of me.
B: Now put it back, and see which one is the brightest.
M: I really can't tell.
B: The candle you took out is the OW you thought the last only women in your life. The so-called love is from your imagination. When you feel you love her, you use your heart to look at her, you think she is the brightest. When you put her back, you can not find any brightness. Your so-called loast only love is just a fantasy.
M: Oh, I understand now, you didn't ask me to D my wife, you were educating me.
B: I did not say that, just go.
M: Now I know whom I truely love, she is my wife.
Well, there is no religious meaning here. I just feel that no matter, where, people all think A is a fantasy.
