What are the gods and Asura fighting for?

Asura was originally a god, including Varuna and other important figures in the Vedic era. The name means "The Last Jay". However, due to the rule of Deva, the Aryan god under Indra, most of Asura was reduced to the devil. They were driven from heaven to hell, usually thought to be at the bottom of the sea. However, the change of their identity cannot protect Vishnu, a great god, which inevitably means the loss of power. A remarkable feature of Indian mythology is that the gods and demons are evenly matched and constantly compete for the hegemony of the three realms. In Indian mythology, God cannot control the kingdom of heaven forever. The war between the gods and Asura was for nectar. At first, the gods attributed their strong physique to their exclusive nectar, but generally speaking, the world attributed this to the sacrifices provided by humans. Demons have been waiting for opportunities to grab nectar, but gods have been strengthened by nectar and can defeat them. Sometimes God uses tricks to stop them from taking nectar. For the devil, especially in later times, they practice asceticism. In this way, we can gain great power to force the gods, especially Brahma, to yield. Many demons are extremely knowledgeable theologians who are good at getting gifts in this way. But God can usually defeat them through pure deception, through their own abstinence, or through secret prayer and similar methods. Although the devil gained strength through asceticism and defeated the gods more and more, the gods also defeated them with their fearless courage and ruled the universe. All their strength can only be released at the end of each era and when they are facing destruction.

Asura can change into any shape at will, which was fully proved when they attacked Clichy under the leadership of the demon king Ganza. Cassim the horse demon is one of them. He is also Indra's opponent. When Cassim led Asura's army against the gods, he threw a big stick at Indra and then a huge stone, but all the thrown objects were broken by Indra with his magic pestle. Indra evaded the attack and defeated Asura.
