The legend of Dasaratha is an eventful one. It is said that Dasaratha during one of his hunting expeditions, heard a noise resembling an elephant's roar from a nearby waterhole, and shot in the direction with an arrow. He was famous for his ability to shoot an arrow just by hearing the noise. Much to his chagrin, he finds that he has instead shot a young boy called Sravana kumar who was collecting water to quench the thirst of his blind parents. Sravana used to carry his parents everywhere on two pans of a balance supported on his shoulders. They were completely dependent on the boy and Sravana was inconsolable at the thought that they will be left without anybody to protect them. He requests the King to carry the water to his parents, as his dying wish. The old couple drink the water, not knowing that it is not being offered by their son.

Kaikeyi saves the king by using her hand as the axle. Touched by this, Dasaratha promises to grant Kaikeyi two boons when she wishes to avail of them.
These two incidents in Dasaratha's life play havoc in the future course of incidents. Kaikeyi demands the three boons from Dasaratha, just before he was going to coronate his eldest son Rama as the king.

The dejected king eventually dies, unable to withstand the anguish over separation from his son, thereby fulfilling the curse of Sravana's father.
