A state of consciousness develops when one feels he has control over all the elements and this comes because of his control over the indriyas. This can lead the person to the feeling of invincibility.

Ravana, the emperor of Lanka did severe penance and appeased Lord Brahma and Lord Shiva and was blessed with boons. He had control over the pancha agnis and therefore became arrogant. He attacked Kubera, drove him out of Lanka and became the King of Lanka. He attacked many kings and devas and defeated them. Though he lost to Vali and Kartaveerya Arjuna, he considered himself invincible. His pride, arrogance, anger and lust became the cause of his downfall. After he abducted Sita, Lord Rama came to Lanka and vanquished him.
