What is the difference between 'Vidya' and 'Avidya' as explained in the text?

Chapter 50 draws a clear distinction between 'Vidya' (knowledge) and 'Avidya' (ignorance). 'Vidya' is described as the pure, eternal pulse of knowing "I am Brahman" and the understanding that "This Soul is Brahman." It is the realization of being the pure witness, enlightened and liberated. In contrast, 'Avidya' is the attitude of thinking, "I am a sinner, unfortunate, luckless." The text states that these are two ancient powers of Maya, where one leads to liberation from bondage and the other leads to the state of bondage itself.
