What is the distinction between true knowledge (Vidya) and ignorance (Avidya) according to the text?

According to Chapter 50, the distinction between Vidya and Avidya is fundamental. True knowledge, or 'Vidya,' is described as the eternal pulse of realizing 'I am Brahman,' understanding oneself as the pure, enlightened, and liberated Soul, the treasure of 'Consciousness is Bliss.' In contrast, ignorance, or 'Avidya,' is the attitude of thinking, 'I am a sinner, unfortunate, luckless.' The text clarifies that these are ancient powers of Maya, where one leads to a state of bondage and the other leads to liberation from that bondage.
