I'm confused about the concepts of Avidya and Maya. Can you explain what they are using the examples from the text?

Avidya, also called Maya, is described in Chapter 50 as a form of ignorance or worldly illusion. It's the root cause of our misperception of reality. The text explains that this delusion makes one thing appear as something else. For instance, it gives the example of a rope being mistaken for a snake, or how shimmering heat waves are perceived as a mirage. Another vivid illustration is how a single lit firebrand, when whirled rapidly, creates the illusion of a solid circle of fire. On a personal level, this illusion manifests as egoic attachments, such as the feeling that 'I am the body, mine are wife and home,' and intellectual pride, which are all considered products of Maya that prevent true knowledge and happiness.
