Sugreeva confident about Ramas capacity to kill Vali

Sugreeva was once and again saying that it was very difficult to kill Vali. Then Lakshmana enquired Sugreeva as what Rama should do to bring confidence in Sugreeva.Then Sugreeva came out with two points. Rama should throw out Dundhubhis corpse to one yojanas distance with his toe. second one is ,he should release his arrow in such a fashion that it passes through one of the saala trees. Sugreeva turned towards Rama and pleaded with him.Rama!I am afraid of Vali.I am worried thinking of his capabilities.I had seen his strength with my eyes.But I had not seen you at war. So,I am worried whether you can equal him in strength and efficiency or not.I am saying these words with fear of Vali. I am not talking like this to humiliate you.Your physique proves your strength. Rama was not offended with Sugreevas words. He smiled and told him that he would show him his capacity. He threw the corpse of Dundhubhi to more than ten yojans distance.But Sugreeva still had his own doubts. He said to Rama.When Vali threw this body, it was wet and full of meat and muscle.It was heavy then. But now,it has dried up and has lighter weight.Vali was tired of fighting with Dundhubhi at that time. But now,you are neither tired nor tensed up regarding victory.So,one can not judge your strength by this act.So, please see that yourarrow passes through one of the sala trees.Rama released his arrow. It passed through all the seven sala tress,the mountain,and entered the earth and came out by tearing the ground and settled at his back. seeing this ,Sugreeva was awe struck. He laid hinself flat at the Rams feet and prayed him.Rama!I am now confident that you can kill Vali.Please kill VALI at this moment itself. Rama hugged Sugreeva and told him to go to Kishkindha first. Then told him to call Vali for a duel.
