Mura has five heads, is well-versed in the art of war and has a large and strong army. He seems to command 11 Akshauhinis forces – (one Akshauhini is about 110,000 soldiers, 65,000 horses, 22,000 chariots and 22,000 elephants. See here for details about Akshauhini)
|The demon Mura tries to defend Naraka's fortress as Krishna and Satyabhama attack on Garuda|
He, along with his seven sons, defend the fortress with success initially, until Krishna hurls his mace and breaks the defense. Krishna then uses his disc Sudarshan Chakra and cuts off Mura’s heads one by one, and then also kills all his sons. This feat earns Krishna the epithet of Murari (‘ari’, or enemy of Mura).
|Krishna and Satyabhama infiltrate all fortresses of Naraka|
Satyabhama feels sorry for the dying demon. Meanwhile Naraka, on his deathbed, also seems remorseful and asks for a blessing from his mother Satyabhama, that his killing be remembered on the earth. This Narakasur Vadh is what is celebrated on the second day of Diwali.
