Can you explain the metaphor of the snake and the rope as it is presented in Chapter 22?

In Chapter 22, the analogy of the snake and the rope is used to illustrate the nature of illusion and the role of the Sadguru. The text explains that in dim light, a rope can be mistaken for a snake, creating fear. This 'snake-like tendency' is an illusion. The Sadguru is described as the creator of both the illusion (the snake) and the one who removes it by revealing the truth (the rope). Furthermore, the chapter notes that before any perception, in 'total darkness,' there was neither snake nor rope, just a formless state, which is also the Sadguru. This powerful metaphor from Chapter 22 teaches that the Guru is the source of the perceived world of illusion, the means to overcome it, and the ultimate formless reality itself.
