How does Chapter 51 explain the concept of 'delusion' versus 'knowledge' by referencing the Bhagavad Gita?

Chapter 51 delves into a subtle spiritual distinction by referencing the Bhagavad Gita. It highlights that at the end of the Gita, Shri Krishna asked Arjuna if his 'delusion' was destroyed, not if he had 'attained knowledge.' Arjuna's response confirmed this, stating, 'My delusion has vanished.' The text of Chapter 51 clarifies that delusion, or 'moha,' is simply another name for ignorance. As explained in this chapter, the core insight for those who understand the Gita is that the destruction of ignorance is the true goal, which is framed as the vanishing of delusion rather than the acquisition of something new called knowledge.
