What do you see that identifies karma?
I would think that one of the best examples of karma is seen in Ravana, himself. Ravana is able to use his knowledge and his own understanding of the Vedas to exercise full power without any regard for the law and the conception of righteousness that is present. His rule is a demonstration of how the satiating of appetites can be the guiding force in consciousness. His taking of Devi Sita, as well as the manner in which he rules is not necessarily one in which there is an adherence to dharma. Rather, Ravana lives in a manner that almost defies such elements. It is interesting to note how Karma works in this setting. When Lord Rama does finally defeat him, it is a statement on how karma is unavoidable. For Ravana, his defeat at the hands of Lord Rama is the ultimate recognition of the power of the Lord. It has been argued that Ravana's actions were directed towards salvation given to him by the Lord Vishnu in the form of Lord Rama. Karma is evident in that Ravana is unable to avoid the reckoning given to him by the Lord. This demonstrates how, at some point, all human beings must be assessed in light of karma of how they lived and carried themselves. Ravana becomes the ultimate example of the power of Karma guiding everyone.
