What is the specific textual point made about the 'Avagraha' in the Bhagavad Gita verse mentioned in this chapter?

In its analysis of a verse from the Bhagavad Gita, Chapter 50 highlights a specific linguistic and philosophical point regarding the 'Avagraha'. The text points to the thirty-fourth verse of the fourth chapter of the Gita and notes that in its third line, an 'Avagraha' appears before the word 'Jnana' (knowledge). The significance of this, as explained in Chapter 50, is that this symbol emerges as an indicator of 'Ajnana,' or ignorance. This suggests a discourse oriented toward ignorance, providing a nuanced interpretation that differs from simply reading the word as 'Jnana,' which is universally accepted as leading to liberation.
