Detachment involves more than just recognizing the defects and weaknesses in objects which results from their transitory nature. Detachment also involves the positive quality of getting the most out of the objects of the world. You should always strive to make the best use of an object and appreciate it for what it is. There is no point in just dwelling on the limitation and sorrow that objects of the world produce, but you should know to properly use objects to perform your duty in the world. Then you will acquire some satisfaction. In the larger sense, it is really giving up worldly sorrow and gaining the bliss of the supreme self that is true detachment. Giving up family, wife, children and properties and then going to the forest cannot be called detachment. Detachment is recognizing the weak aspects in the nature of the objects, as well as accepting their positive and strong points.
Whenever you get into difficulty, whether physical, mental, financial or any other type of problem, you may develop a sense of detachment towards the objects causing this state. This is quite natural. For example, suppose a person dies and his body is taken to the burning ground where it is cremated. When you look at such a situation you develop a particular type of detachment, philosophizing that the body has to come to an end some time or another. But this detachment is only a temporary phenomenon, a temporary feeling; it cannot be considered true detachment.
Another example is when a mother is delivering her first baby. Not being able to suffer the pain, she shouts that she would rather die. This also is not true detachment. As soon as the baby is born, suppose she has a girl, she immediately wants to get a boy the next time. A similar situation develops when someone does not get his wishes fulfilled. Here also he develops a certain type of detachment. All these attitudes are temporary. Permanent detachment is something quite different.
Permanent detachment is an intense detachment, as opposed to dull or weak detachment. For example, a person may have resolved to go on a pilgrimage to one of the holy places in India, but then there may be a strong tendency to postpone it to the next month. If it is a matter of doing something good such as going on a pilgrimage, one will tend to postpone it. On the other hand, if it is a matter of doing something bad, one prefers to do it right on the spot, without wasting any time. People usually will not make very great efforts to perform good deeds. This may be seen as a type of weak detachment which tends to postpone implementing good resolutions and performing good actions. But such behavior will not help you to reach your spiritual goal. It is intense detachment which is essential for progress on the spiritual path.
