What is the difference between true knowledge (Jnana) and ignorance (Avidya) as described in the scriptures?

The scriptures differentiate between true knowledge (Jnana) and ignorance (Avidya) based on one's core self-perception. Chapter 50 explains that Jnana is the profound understanding that "I am the Soul, the pure witness" and the recognition that "This Soul is Brahman." This pure knowledge, or 'Vidya', is the eternal pulse of "I am Brahman." Conversely, Avidya, or ignorance, is described as the attitude of thinking, "I am a sinner, unfortunate, luckless." As stated in Chapter 50, from these two ancient powers of Maya, one leads to liberation through knowledge, while the other leads to a state of bondage through ignorance.
