Based on Chapter 51, what is the distinction between 'attaining knowledge' and the 'destruction of delusion'?

Chapter 51 makes a subtle but important distinction between attaining knowledge and destroying delusion by referencing the Bhagavad Gita. The text highlights that Shri Krishna asked Arjuna if his delusion was destroyed, not if he had gained knowledge. Arjuna's reply affirmed the destruction of his delusion. The author then clarifies that 'delusion (moha) is merely another name for ignorance.' Therefore, as presented in Chapter 51, the core spiritual achievement is the removal of ignorance, which is a prerequisite for true understanding, rather than the mere acquisition of facts or intellectual knowledge.
