Mahabali

In the story of Mahabali, Even though Mahabali was a good person, he had forgotten humility when he became powerful. He underestimated the power of the little man who visited him, who was none other than Vishnu himself. We never know in what form God may appear before us and hence we should never forget to be humble.

With power comes responsibility

In Ramayana, we also see the sixth avatar of Vishnu, who was Parasurama. Vishnu took the Avatar as Parasurama to control the dominance of Kshatriyas. Parasurama even though born as a Brahmin, had great power by god's grace. After he taught a lesson to the Kings and the Kshatriya race, he did not stop. He continued destroying them. He forgot his true responsibility. Only after Rama defeated him in a combat, Parasurama realized his folly.
