How do the opening verses of Chapter 22 characterize the Sadguru?

The invocations at the beginning of Chapter 22 offer a profound characterization of the Sadguru. He is hailed as the 'embodiment of bliss,' the 'form of knowledge,' and the 'supreme purifier.' The verses celebrate him as the 'destroyer of the fear of worldly existence' and the 'burner of the sins of Kali-yuga.' Furthermore, as mentioned in Chapter 22, the Sadguru is likened to an 'ocean of bliss' from which various mental tendencies arise, yet He is also the one who alone can restrain them. This powerful introduction establishes the Sadguru as a complete, merciful, and supreme being who is the source of all and the ultimate remover of fear and illusion.
