In due course of time, when the body becomes old and practically invalid, it is subject to jarā, the sufferings of old age. There are four basic kinds of suffering — birth, old age, disease and death. No scientist or philosopher has ever been able to make a solution to these four miserable conditions. The invalidity of old age known as jarā is figuratively explained here as the daughter of Time. No one likes her, but she is very much anxious to accept anyone as her husband. No one likes to become old and invalid, but this is inevitable for everyone.
