Based on the analysis in Chapter 51, what was Arjuna's specific acknowledgement to Shri Krishna, and what is the significance of his word choice?

Chapter 51 provides a detailed analysis of Arjuna's response to Shri Krishna in the Bhagavad Gita. It highlights that when Krishna asked if his delusion was destroyed, Arjuna's specific acknowledgement was, 'My delusion has vanished to the ends of the earth.' The significance, as pointed out in Chapter 51, is that Arjuna did not claim to have 'attained' knowledge, but rather that the 'destruction of delusion has occurred.' The text emphasizes that delusion (moha) is simply another name for ignorance, and its destruction is the key outcome, a point central to the spiritual understanding presented.
