Why does Chapter 51 emphasize the distinction between 'destroying delusion' and 'attaining knowledge'?

Chapter 51 emphasizes this distinction to highlight a core spiritual principle using an example from the Bhagavad Gita. It points out that Shri Krishna's specific question to Arjuna was about the destruction of delusion, and Arjuna's response confirmed that his delusion had vanished. The chapter clarifies that delusion, or 'moha,' is synonymous with ignorance. As explained within Chapter 51, the focus is on the removal of this negative state. The destruction of delusion is the fundamental step, the primary cause, while the attainment of knowledge is its natural effect. This prioritizes purification and the removal of spiritual blockages as the true path to enlightenment.
