Can you explain the philosophical analogy of the snake and the rope mentioned in Chapter 22?

Chapter 22 uses the classic analogy of mistaking a rope for a snake to describe the Sadguru's nature. It posits that in dim light, a rope can be perceived as a snake, creating fear. Sai Baba is described as the source of both the illusion (the 'snake-like tendency') and the reality (the 'rope'). The text states that He is the creator of this fear and also the one who ultimately removes it by revealing the truth. Furthermore, the chapter explains that before this perception, in 'total darkness,' there was neither snake nor rope, and this formless, primordial state is also the Guru. This analogy illustrates the Guru's role as the master of illusion and the bestower of true knowledge.
