Can you explain the philosophical description of the Sadguru at the beginning of Chapter 22, including the snake and rope analogy?

Chapter 22 begins with a profound philosophical description of the Sadguru, Sai Baba, hailing him as the embodiment of bliss and the destroyer of worldly fears. The text uses the classic analogy of a snake and a rope to explain his divine nature. In dim light, a rope might be mistaken for a snake, creating fear. The Sadguru is presented as the master of this perception; he is the "creator of the snake-like tendency" (illusion) and also the one who reveals the truth as a rope, thereby removing the fear. As Chapter 22 explains, he is the formless origin, the cause of the illusion, and ultimately the one who dispels it, showing his complete control over reality and perception.
