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

In Chapter 22, the Sadguru's power over illusion and reality is explained through the metaphor of a snake and a rope. The text describes how in dim light, a rope can be mistaken for a snake, creating fear. The Sadguru is presented as both the creator of this illusion, or "snake-like tendency," and the one who removes it by revealing the truth, the "form of a rope." This chapter beautifully illustrates that He is the source of fear and, ultimately, the one who removes it, being the master of both the perceived reality and the ultimate truth behind it.
