Based on the invocations in Chapter 22, what is the ultimate, unknowable nature of the Sadguru?

Chapter 22 portrays the Sadguru, Sainath, as a being of profound and paradoxical nature. He is hailed as the 'embodiment of bliss' and the 'destroyer of the fear of worldly existence.' However, his ultimate reality is described as being beyond comprehension. The chapter states that his nature is 'devoid of being and non-being,' a state so deep that 'no one can find its place.' It emphasizes this incomprehensibility by noting that the Vedas became silent in their attempts to describe him, and even Shesha, the celestial serpent with countless mouths, cannot grasp his true reality. This establishes the Guru's essence as supreme and fundamentally beyond the limits of mortal understanding and praise.
