Can you analyze the distinction between the 'destruction of delusion' and the 'attainment of knowledge' as presented in Chapter 51's commentary?

Chapter 51 presents a subtle but profound spiritual analysis by distinguishing between the destruction of delusion and the attainment of knowledge. It highlights that Shri Krishna asks Arjuna if his delusion (moha) is destroyed, and Arjuna confirms its vanishing. The text in Chapter 51 emphasizes that delusion and ignorance are essentially the same thing. The key insight offered is that spiritual realization is not about acquiring something new called 'knowledge,' but rather about removing the pre-existing state of ignorance. Therefore, the 'destruction of delusion' is the primary event, and the attainment of knowledge is its natural consequence, a concept that Chapter 51 states is understood by those who know the Gita's true essence.
