Can you elaborate on the distinction between the 'destruction of delusion' and the 'attainment of knowledge' as presented in Chapter 51?

Chapter 51 presents a nuanced spiritual point by analyzing a dialogue from the Bhagavad Gita. It distinguishes between destroying delusion and attaining knowledge by highlighting Shri Krishna's specific question to Arjuna: "has your delusion been destroyed?" Arjuna's affirmative response focuses on the vanishing of his delusion, not the acquisition of new knowledge. As explained in Chapter 51, delusion, or 'moha', is just another word for ignorance. Therefore, the emphasis is on removal of this ignorance rather than the addition of knowledge. This suggests that enlightenment is a process of subtraction—eliminating the false—which then allows the inherent truth or knowledge to manifest on its own.
