How does Chapter 22 use the analogy of a snake and a rope to explain the Sadguru's power over illusion?

In Chapter 22, the text employs a classic philosophical analogy to describe the Sadguru's role in both creating and dispelling illusion. It compares the state of illusion to seeing a snake in dim light, which is later revealed to be merely a rope when proper light is introduced. The chapter states that the Sadguru is the source of both the dim light (illusion) and the true light (reality). He is described as the "creator of the snake-like tendency" and also the one who ultimately "removes" the fear by revealing the truth, which is the "form of a rope." This illustrates his supreme command over perception and reality.
