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

Chapter 22 presents a profound philosophical teaching using the analogy of a snake and a rope. It explains that in dim light, a rope can be mistaken for a snake, creating fear. This represents the illusion of worldly existence. The Sadguru, Sai Baba, is described as the light of knowledge that reveals the rope's true nature, thus dispelling the fear and illusion. Furthermore, the text states that the Guru is the ultimate source of both the illusion (the snake-like tendency) and its removal, being the formless reality that existed even before the rope or the snake appeared. This illustrates the Guru's supreme power over perception and reality.
