Apart from Happiness the four motives are described below.

First one is life. Everyone wants to live till infinity. No one wants to die. Death is most dreaded of all. Why? The simple reason that on death there is an end to the physical existence of anyone in the physical body. Since all the concepts of happiness are related to happiness through senses, there is spine chilling fear when death approaches. Nothing is known to mortals about the course after the death.

There is a fear that all loved ones and all loved objects will be lost forever. The person would remain all alone. What will be the fate after death?

There is some description available from Garud Puran, a Hindu scripture, that deals with after death path of a soul.
