How does Chapter 50 use analogies to explain the illusory nature of the world?

Chapter 50 illustrates the deceptive play of Maya, or Avidya, using several powerful analogies to show how things are not as they appear. It mentions how a rope can be mistaken for a snake, or how the inside of a shell can create the illusion of silver. The text also points to the phenomenon of a mirage, which people see in the sun's rays but is not real water. A particularly vivid example given in Chapter 50 is that of whirling a lit firebrand, which creates the appearance of a continuous circle of fire, even though the fire-circle itself doesn't truly exist. This is how Maya produces a non-existent world.
