The moral is:
Before marriage, he is the half body. Before marriage, she is the half body. Lady has always left the side. The right side is gents. The gent’s body is always the right side of the wife. After Marriage, Now you have only one body. In Hindu philosophy or custom, this is called arrange. (Ardha means half.) Wife before marriage is only ardhangi, half body. Now the left side is joined with the right side and you are full body.
