How does Chapter 51 use a dialogue from the Bhagavad Gita to explain the concept of destroying delusion?

Chapter 51 of the Sai Satcharitra references a key dialogue from the end of the Bhagavad Gita between Shri Krishna and Arjuna to illustrate the nature of destroying delusion. The chapter points out that Krishna specifically asked Arjuna, "has your delusion been destroyed?" rather than asking if he had attained knowledge. In response, Arjuna confirmed, "My delusion has vanished." The text emphasizes that delusion, or 'moha', is simply another name for ignorance, and its destruction is the crucial step, a nuance that those who know the essence of the Gita understand.
