What is the relationship between destroying ignorance and attaining knowledge as explained in Chapter 51's reference to the Bhagavad Gita?

Chapter 51 explores the relationship between ignorance and knowledge by referencing the dialogue between Shri Krishna and Arjuna. The chapter explains that at the conclusion of the Gita, Krishna asks if Arjuna's delusion (moha) is destroyed, not if knowledge is attained. Arjuna confirms that his delusion has vanished. As Chapter 51 clarifies, delusion and ignorance are essentially the same thing. The focus is on the removal of a negative state (ignorance) rather than the active acquisition of a positive one (knowledge). The text implies that the destruction of delusion is the primary goal and the true essence of the teaching, a subtle but important distinction highlighted in Chapter 51.
