Can you explain the snake and rope analogy used in Chapter 22 to describe Sadguru Sainath's nature?

In Chapter 22, the analogy of the snake and the rope is used to explain the nature of illusion and reality in relation to the Sadguru. The text explains that in dim light, a rope can be mistaken for a snake, which creates fear. This 'snake-like tendency' represents illusion or maya. According to the teachings in this chapter, the Sadguru is described as the creator of both the illusion (the snake) and the one who reveals the reality (the rope). Ultimately, as Chapter 22 states, He is also the formless reality that existed before either the snake or the rope appeared, being the one who creates fear through illusion and the one who removes it by revealing the truth.
