How does the text use analogies like the rope and snake or the whirling firebrand to explain Maya?

Chapter 50 provides several powerful analogies to help explain the deceptive nature of Maya, or worldly illusion. For instance, it describes how a rope can be mistaken for a snake, how a shell can appear to hold silver, or how the sun's rays can create the illusion of a mirage. In each case, the object is one thing but appears as something else. Another example given is whirling a lit firebrand, which creates the illusion of a continuous circle of fire (Agni-kankan), even though the fire itself is just a single point. Chapter 50 uses these examples to illustrate how Maya operates, producing a non-existent, illusory world from the reality of Brahman, fooling even the wise.
