Four Directions

Before dawn he used to go 

1. from the Eastern coast of sea to the Western coast and 
2. from the Northern coast of the sea to the Southern coast to pay his homage to Surya - the sun-god.

He was so brave and powerful that on his way to pay homage to Surya, he used to toss the mountain peaks upward and catch them as if they were play balls.After completing the tedious task of paying homage to the sun god in all four directions, he used to return to Kishkindha without even being tired .

Once Ravana called Vali for a fight when Vali was doing his regular Sandhyavandanam. He took Ravana in his tail and took him around all the world. Humbled, Ravana called for atruce. It is said in the Ramayana that Vali was very brave and courageous.

Three Gunas

Ravana was Rajasic, drunk with power, passion and self-destructive behavior; his brother Kumbakarna was Tamasic with sloth and slumber; the other brother Vibhishana was Sattvic, left his brother Ravana, joined Rama's camp and surrendered to Him. This is one of the most celebrated Surrenders (Saranagati, Prapatti) to Rama.

Rama crowned Vibhishana, of the serene temperament, King of Lanka, and destroyed Ravana and Kumbhakarna, who symbolised Rajasik and Thamasik qualifies.

Bhasmalochan

As Ram was about to place his foot on the is- land, Vibhishana noticed a rakshasa approaching . The army; he was blindfolded. ‘That is Bhasma- lochan,’ he informed Ram. ‘If he removes his blindfold, all that he will see will burst into flames and be reduced to ashes.’ Ram immediately shot an arrow that transformed into a mirror. That was the first thing Bhasma- lochan saw when he removed his blindfold. He who was sent to set aflame Ram’s army saw his own reflection and was himself reduced to ashes.
