Shrutayudh and Bhasmasur

Both the devils had got boons due to their austerities. It was their immoral intelligence, which made them to choose such things that ultimately became the cause of their deaths. Shrutayudh had got a Gada, which he had got by the boon from Lord Shiva on the condition that he would not misuse it. If he did then it would in turn destroy him. In the battle of Mahabharata, in a fit of anger he used it on Shri Krishna who was charioteer of Arjun. The Gada returned from midway and tore him apart. Bhasmasur had asked for a boon that the person would be destroyed if he places his hand on his head. When he started misusing this power, God created illusion and made him keep his hand on his own head, which resulted in his death.
It is the direction of choice that decides our destiny and future.
