What is the philosophical significance of the Sadguru as described in the opening verses of Chapter 22?

The opening verses of Chapter 22 portray the Sadguru, Sai Baba, as the supreme and absolute reality. He is described as the "destroyer of the fear of worldly existence" and the "burner of the sins of Kali-yuga." The chapter uses a powerful metaphor, stating that the Guru is the creator of illusion (the snake), the revealer of truth (the rope), and also the formless state that existed before either. This establishes the Guru as the source of both perception and reality itself. The text emphasizes that this true nature is so profound that even the Vedas fall silent and celestial beings cannot fully comprehend it, highlighting the Guru's incomprehensible and ultimate divinity.
