The text mentions Maya and gives examples like a rope appearing as a snake. Could you elaborate on this concept of illusion?

The concept of Maya, or worldly illusion, is explained as the power that causes things to appear as something other than what they truly are. Chapter 50 illustrates this with several powerful examples. Just as a rope can be mistaken for a snake in the dark, or a shell can appear to contain silver, Maya creates a false perception. Another example given is how the sun's rays can create a mirage. A particularly vivid illustration is whirling a lit firebrand (kolit), which creates the visual illusion of a complete 'circle of fire' (Agni-kankan), even though the circle itself doesn't really exist. In the same way, the delusion of Maya produces a non-existent world, which seems real to us.
