How does Chapter 22 explain the concept of illusion versus reality through the metaphor of the snake and the rope?

Chapter 22 of the Shri Sai Satcharitra delves into a deep philosophical concept using a classic analogy. It describes the Sadguru as being the source of both illusion and its removal. In dim light, a rope can be mistaken for a venomous snake, creating fear. The text explains that the Guru is the creator of this snake-like illusion (maya) but is also the one who, like a bright light, reveals the truth that it is merely a rope, thereby removing the fear. This powerful metaphor, found in Chapter 22, illustrates the Guru's role in guiding devotees from the fearful illusions of worldly existence to the true, blissful reality.
