How does Chapter 50 explain the difference between true knowledge (Vidya) and ignorance (Avidya)?

Chapter 50 draws a clear distinction between true knowledge and ignorance by defining their core attitudes. It states that 'Vidya', or pure knowledge, is the eternal pulse of recognizing "I am Brahman," the pure, enlightened, and liberated soul. In contrast, 'Avidya', or ignorance, is described as the attitude of seeing oneself as a "sinner, unfortunate, luckless." The chapter explains that from one of these ancient powers of Maya comes bondage, and from the other comes liberation. This distinction is presented as fundamentally important, as the text reinforces the Vedic principle that "Only from knowledge comes liberation."
