Bad action is represented by Ravana. He had all wealth and learnt 64 types of knowledge. He even learnt the languages of animals and birds. Rama knew only 36 types of knowledge. Rama lived in the forest while Ravana lived in a kingdom. Ravana was no less than Rama in strength. In spite of all this, Ravana kidnapped the wife of another person and so he was killed by monkeys. No one keeps the name of Ravana. (M, pp. 78-79)
