Based on Chapter 16, what is the purpose of the Sadguru's incarnation, and what are some of his divine attributes?

Chapter 16 of Sai Satcharitra explains that the Sadguru, hailed as the 'King of Yogis,' has taken a physical body for a selfless purpose: 'for the sake of helping others, to uplift the poor and lowly.' His divine nature is described with several powerful attributes. He is called the 'Idol seated on the throne of peace' and the 'Lord of the Empire of Self-Bliss.' The chapter further extols his virtues with titles such as Stainless (Niranjana), Imperishable (Avyaya), and the One beyond attributes (Gunatita). This depiction in Chapter 16 emphasizes that while he appears in a human form, his true nature is divine and his mission is purely compassionate.
