What philosophical teachings about the Sadguru's nature are presented in the opening verses of Chapter 22?

The opening of Chapter 22 presents profound philosophical teachings about the Sadguru's divine nature. He is hailed as the "destroyer of the fear of worldly existence" and the "burner of the sins of Kali-yuga." The text describes him as an "ocean of bliss" from which various mental tendencies arise, which he alone can restrain. A key teaching uses the analogy of a rope mistaken for a snake to explain illusion. The Sadguru is identified as the source of both the illusion (the snake) and the reality (the rope), as well as the fear it creates and the knowledge that removes it. Chapter 22 states that his true reality is so profound that even the Vedas fall silent and cannot comprehend it.
