How does Chapter 22 philosophically position the Sadguru in relation to reality, illusion, and the limits of knowledge?

Chapter 22 portrays the Sadguru as a supreme and paradoxical entity who governs both reality and illusion. Using the snake-and-rope metaphor, the text establishes the Guru as the source of illusion (the snake) and the dispeller of it (the light revealing the rope). This demonstrates his dominion over the devotee's perception and the fear of worldly existence. The chapter elevates the Sadguru beyond conventional understanding by stating that even the Vedas became silent in their attempt to describe him, and the celestial serpent Shesha does not know his true reality. Therefore, as presented in Chapter 22, the Sadguru is depicted as the ultimate, incomprehensible reality, the 'form of knowledge' whose feet are the only path to absolute fulfillment.
