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

According to Chapter 50, the distinction between 'Vidya' and 'Avidya' lies in one's core self-perception. 'Vidya' is described as the eternal pulse of realizing "I am Brahman," the pure, enlightened, and liberated Soul that is the treasure of 'Consciousness is Bliss.' In contrast, 'Avidya' is characterized as the mine of ignorance, an attitude where one sees oneself as a "sinner, unfortunate, luckless." The text explains that from the former comes liberation from bondage, while the latter reinforces the state of bondage, highlighting how our internal convictions shape our spiritual reality.
