How does Chapter 22 describe the Sadguru's relationship with illusion, using the snake and rope analogy?

Chapter 22 poetically explains the Guru's role in both creating and dispelling illusion through the metaphor of a snake and a rope. The text states that in dim light, a rope might be mistaken for a snake, creating fear. The Guru is described as the creator of this "snake-like tendency" or illusion. However, as also mentioned in Chapter 22, the Guru is ultimately the one who brings the light, revealing the rope for what it is and removing the fear. This illustrates that the Sadguru is the source of both the illusion that binds us to worldly existence and the knowledge that liberates us from it.
