Based on the introductory chapter, what is the nature of the Sadguru, and why is he described as compassionate?

The introductory chapter portrays the Sadguru as the supreme, ultimate reality and a being of immense compassion. Chapter 1 describes the Sadguru, Shri Sainath, as the "ocean of mercy" and the "compassionate one." His nature is so profound that the Vedas fall silent in trying to describe him, and his dwelling is beyond Maya, or the "Unmanifest" that gives birth to the universe. He is the foundation of all existence, the soul of all, and the giver of intellectual inspiration. The author concludes his initial salutations by surrendering with body, speech, and mind to the Sadguru, emphasizing that this final bow is the "sweetest morsel," which underscores the Guru's supreme and merciful status.
