What is the difference between true knowledge (Jnana) and ignorance (Ajnana) as explained in the text?

According to the teachings in Chapter 50, the fundamental difference lies in one's self-perception. True knowledge, or 'Vidya', is the unwavering understanding that "I am Brahman," the pure, enlightened, and liberated soul. It is the recognition of the self as the treasure of 'Consciousness is Bliss.' In contrast, ignorance, or 'Avidya', is the attitude of seeing oneself as a sinner, unfortunate, or luckless. This chapter further explains that even a person considered wise can possess knowledge that is actually ignorance if their mind is fixated on worldly attachments like wealth and family, as this deludes them from their own true welfare.
