How does Chapter 22 describe the profound and unknowable nature of the Sadguru?

In its opening verses, Chapter 22 portrays the Sadguru as a being of immense depth, the 'embodiment of bliss' and the 'form of knowledge.' His true nature is described as being beyond human comprehension. The text explains that before illusion existed, there was a formless state, and that formless one is also the Guru. It emphasizes this incomprehensibility by stating that because of his profound nature, 'the Vedas became silent' and even the celestial serpent Shesha 'does not know the true reality.' This highlights the Sadguru's supreme and transcendent state, which cannot be fully grasped or articulated.
