Meaning: I don't know where the feelings begin, but they are getting deeper and deeper. I don't know where the resentment has gone, but when I smile at each other, the resentment will naturally disappear.

I don't know what the situation is, but it keeps going. The living can die and the dead can live. People who are born but can't be born and die, and those who die but can't be resurrected, are not affectionate. -Tang Xianzu's Peony Pavilion

Emotions are aroused unconsciously, and deeper and deeper. You can die for it when you are alive, and live for it when you are dead. Those who live and don't want to die for love, and those who die and can't be resurrected, can't be regarded as the acme of feelings.
