The Death Of Mahishasura
Mahishasura, was a demon who unleashed evil and terror all over the world. He could not be killed by Lord Shiva, Lord Brahma and Lord Vishnu. This was because of a boon granted by God Brahma to Mahishasura according to which he would not be destroyed by any deity or man. With the combined forces of all the Gods, Mahadevi was created who was neither goddess nor human. With her fierce lion as her carrier, Goddess Durga Mahadevi rode towards the lair of Mahishasura. After 9 days of continuous battle the demon was finally beaten. Thus, Mahadevi also came to be known as Mahishasura Mardhini the slayer of Mahishasura.
Lord Rams Victory
Before confronting Ravana, Lord Ram sought the blessings of Goddess Durga by performing the Chandi Puja. To perform the Puja, Rama required 108 blue lotuses, but he had only 107 of them. Instead, he offered his own eye that resembled a lotus and placed it at the feet of the Goddess. Pleased with his devotion and pure mind, Goddess Durga saved Rama while he was at battle and blessed him with power of being invincible. Thus, Lord Ram defeated the 10 headed demon king Ravana with Goddess Durgas blessings.
