In English
I shall illustrate this by a small example. A mother longed for the birth of a son and her wish was granted. She gave birth to a son but unfortunately the next day he developed high temperature and died. Is this a matter of joy or sorrow? That birth which was considered the source of joy turned out to be a cause for her anguish. Before the birth, she had undergone the pangs of birth. The same mother, when she looked at the face of her baby, forgot all her pain and was happy. What she considered to be a source of joy turned out to be one of sorrow and what she considered to be sorrow turned out to be delight.
