What philosophical descriptions of the Sadguru are offered in the invocations of Chapter 22?

The opening verses of Chapter 22 offer profound philosophical descriptions of the Sadguru, Sai Baba. He is hailed as the 'embodiment of bliss,' the 'supreme purifier,' and the destroyer of worldly fears. The chapter describes Him as an 'ocean of bliss' from which all mental tendencies arise. He is portrayed as the ultimate reality, both the creator of illusion and the one who dispels it. This divine nature is so deep and beyond comprehension that, as the text states, the Vedas became silent, and even the celestial serpent Shesha could not grasp His true reality.
