How does Chapter 22 use the metaphor of a snake and a rope to explain the nature of illusion and the role of the Sadguru?

Chapter 22 employs a classic philosophical metaphor to illustrate the concepts of illusion (maya) and reality. The text explains that in dim light, a rope can be mistaken for a snake, creating fear, but in proper light, the truth—that it is just a rope—is revealed. According to the teachings in this chapter, the Sadguru is the master of this entire play of perception. He is described as the "creator of the snake-like tendency" (illusion) and also the one who gives it the "form of a rope" (reality). Ultimately, as Chapter 22 clarifies, the Guru is the one who creates the initial fear arising from this confusion and is also the one who removes it, guiding the devotee from the darkness of ignorance to the light of true knowledge.
