Could you explain what Maya is using the examples given in the text?

Chapter 50 uses several powerful analogies to explain the illusory nature of Maya. It is likened to seeing a snake where there is only a rope, or perceiving silver in a mother-of-pearl shell. Another example is how the sun's rays can create the illusion of a mirage. A particularly vivid illustration is that of a person whirling a lit firebrand (kolit); while the fire is real, the 'circle of fire' (Agni-kankan) it appears to create does not actually exist. The text explains that, in the same way, the delusion of Maya produces a non-existent world from the reality of Brahman, a play that can fool even the wise.
