The meanings of Deepavali, its symbols and rituals, and the reasons for celebration are innumerable. It commemorates Lord Krishna's victory over the demon Narakaasura who had kidnapped and terrorized the gopis of Vrindavan.
When the evil Naraka was finally killed by Lord Krishna and Satyabhaama, he begged pitifully for mercy; thus, upon his entreaties, it was declared that this day of his death would be celebrated with great joy and festivity.
