According to Chapter 50, what is the fundamental difference between 'Vidya' (knowledge) and 'Avidya' (ignorance)?

Chapter 50 draws a clear distinction between 'Vidya' (knowledge) and 'Avidya' (ignorance). 'Vidya' is described as the eternal pulse of knowing "I am Brahman," understanding oneself as the pure, conscious, and liberated Soul. It is the realization that "This Soul is Brahman" and "Consciousness is Bliss." In contrast, as the chapter explains, 'Avidya' is an attitude rooted in negativity and self-deprecation, such as feeling "I am a sinner, unfortunate, luckless." The text states that these are two ancient powers of Maya; while Vidya leads to liberation from bondage, Avidya creates the state of bondage for the soul.
