Happiness from detachment:the hindu perspective

Hindu philosophy advocates happiness from detachment.
You get unhappy when you are attached to something.For example why do you feel unhappy, when your pet animal dies?And why are you not unhappy when an animal somewhere distant dies.
The cause of this is attachnment.If you have minimum attachment the minimum unhappiness.This does not mean that you have to be a stone.
Being a human being, being good and considerate to others you can still be detached. What happens when a good surgeon get attached to a patient and cannot afford to hurt him.
The surgeon must be able to do his duty without falling prey to emotions and attachments.
