According to the analysis in Chapter 51, what is the distinction between the destruction of delusion and the attainment of knowledge as discussed in the Bhagavad Gita?

Chapter 51 provides a nuanced analysis of the interaction between Shri Krishna and Arjuna from the Bhagavad Gita to explain a spiritual principle. It points out that at the end of the Gita, Krishna specifically asks Arjuna if his "delusion has been destroyed," not if he has "attained knowledge." Correspondingly, Arjuna's reply is, "My delusion has vanished to the ends of the earth," explicitly stating that the destruction of delusion has occurred, rather than claiming to have 'attained' knowledge. As Chapter 51 clarifies, delusion (moha) is simply another name for ignorance, and their destruction is the key outcome. This distinction emphasizes that the removal of ignorance is the primary goal, which then allows knowledge to manifest.
