When we eat that exquisite piece of chocolate- it is important to recognize that it is not that chocolate we desire. Instead we desire the person who will be happy once he eats that chocolate – we desire the pleased self.
So when someone asks for help – it is not the task at hand(or the favour itself) that we desire. Instead we desire the pleased Person B, which in turn will make us pleased. As always, we desire the pleased self.
For next time you are asked to wash the dishes 🙂
