What does this chapter say is the relationship between knowledge, sinful karma, and achieving liberation?

Chapter 50 lays out a clear, sequential relationship between these concepts. It affirms the unassailable Vedic theorem that "Only from knowledge comes liberation." However, it immediately adds a critical condition: the dawn of this liberating knowledge is impossible without the destruction of sinful karma. This implies that one cannot simply acquire knowledge to be free. First, one must engage in practices that purify them of past sinful karma. Only after this purification can the mind become clear enough for true knowledge to arise, which then leads to liberation from the bondage of Maya.
