There is a plan for material nature, personally known as Durga, to punish the demons. Although the asuras, the godless demons, struggle for existence, they are directly attacked by the goddess Durga, who is well equipped with ten hands with different types of weapons to punish them. She is carried by her lion carrier, or the modes of passion and ignorance. Everyone struggles very hard to fight through the modes of passion and ignorance and conquer material nature, but at the end everyone is vanquished by nature’s laws.
