How does Chapter 51 utilize the Bhagavad Gita to explain the concept of destroying delusion?

Chapter 51 delves into the concept of delusion by referencing a key exchange in the Bhagavad Gita. The text points to the end of the eighteenth chapter, where Shri Krishna asks Arjuna if his delusion has been destroyed, rather than asking if he has attained knowledge. As cited in Chapter 51, Arjuna confirms this, stating, "My delusion has vanished." The Satcharitra emphasizes that delusion (moha) and ignorance are synonymous. It further reinforces this by quoting Arjuna from the eleventh chapter of the Gita: "By the words You have spoken, this delusion of mine has vanished," thereby highlighting that the destruction of ignorance is the paramount goal.
