Can you explain the connection made in Chapter 51 between the destruction of delusion and the teachings of the Bhagavad Gita?

Chapter 51 draws a direct parallel to the Bhagavad Gita to illustrate the concept of destroying delusion. It references the end of the eighteenth chapter, where Shri Krishna specifically asks Arjuna if his delusion has been destroyed, not if he has attained knowledge. Chapter 51 highlights Arjuna's response: "My delusion has vanished to the ends of the earth," emphasizing that the destruction of delusion, or 'moha,' is the key outcome. The text clarifies that 'moha' is simply another name for ignorance and that this is the essence realized by those who know the Gita, serving as a prelude to the new stories being introduced.
