What is the difference between knowledge (Jnana) and ignorance (Avidya) according to the text?

As detailed in Chapter 50, the distinction between knowledge and ignorance is based on one's core self-perception. True knowledge, or 'Vidya', is the realization that "I am the Soul, the pure witness," and the understanding that "'I am Brahman' is the eternal pulse." This is the path to liberation. Conversely, ignorance, or 'Avidya', is described as an attitude of feeling like "a sinner, unfortunate, luckless." This mindset is the very source of bondage. The text emphasizes that from one of these ancient powers of Maya comes bondage, and from the other comes liberation.
