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

According to the teachings in chapter 50, the distinction between Vidya (knowledge) and Avidya (ignorance) is a matter of one's core attitude. The text explains that the eternal pulse of 'I am Brahman' is pure Vidya, leading to liberation. Conversely, Avidya is described as the mine of ignorance, characterized by attitudes like 'I am a sinner, unfortunate, luckless.' From these two ancient powers of Maya, one leads to a state of bondage, while the other brings liberation. The text further clarifies that a person deluded by worldly attachments, constantly thinking of wife and sons, possesses a form of knowledge that is actually ignorance.
