Once you are in a relationship you start taking each other for granted. That's what destroys all love affairs. The woman thinks she knows the man, the man thinks he knows the woman. Nobody knows either. It is impossible to know the other, the other remains a mystery. And to take the other for granted is insulting, disrespectful.
To think that you know your wife is very very ungrateful. How can you know the woman? How can you know the man? They are processes, they are not things. The woman that you knew yesterday is not there today. So much water has gone down the Ganges; she is somebody else, totally different. Relate again, start again, don't take it for granted.
And the man that you slept with last night, look at his face again in the morning. He is no more the same person, so much has changed. So much, incalculably much, has changed.
That is the difference between a thing and a person. The furniture in the room is the same, but the man and the woman, they are no more the same. Explore again, start again.
That's what I mean by relating.
