The text discusses 'Vidya' and 'Avidya'. Can you explain the difference between these two concepts?

Chapter 50 draws a clear distinction between 'Vidya' (pure knowledge) and 'Avidya' (ignorance). 'Vidya' is described as the eternal pulse of understanding "I am Brahman" or "This Soul is Brahman," which is the treasure of 'Consciousness is Bliss.' This leads to liberation from bondage. In contrast, 'Avidya' is defined as the attitude of seeing oneself as a "sinner, unfortunate, luckless." This mindset is considered the source of bondage. The text clarifies that these are two ancient powers of Maya, with one leading to a state of bondage and the other to liberation from it.
