Based on the text in Chapter 51, analyze the significance of the distinction between destroying delusion and attaining knowledge.

Chapter 51 highlights a key spiritual insight by analyzing the dialogue between Krishna and Arjuna from the Bhagavad Gita. The text points out that Krishna specifically asked if Arjuna's "delusion" was destroyed, and Arjuna confirmed his "delusion has vanished." The significance of this, as explained in Chapter 51, is that delusion (moha) is equated directly with ignorance. The focus is on the removal of this negative state rather than the acquisition of a positive one. This implies that knowledge is not something to be added, but is what remains or manifests once the obstacle of delusion is completely removed.
