The Vedas state, 'Only from knowledge comes liberation.' What preconditions does Chapter 50 say must be met for this knowledge to arise?

While Chapter 50 fully endorses the unassailable Vedic theorem that "Only from knowledge comes liberation," it introduces a critical precondition for that knowledge to manifest. The text explicitly states that the dawn of this liberating knowledge is impossible without the destruction of one's sinful karma. This suggests that ethical purification and spiritual discipline are necessary foundational steps. Only after cleansing oneself of past negative actions can a person create the pure internal state required for true knowledge to emerge. Once this pure knowledge is attained, the individual can abandon Maya by their own resolve and is freed from its bondage and modifications.
