Based on Chapter 16, why did Sai Baba, who is described as being beyond attributes, take a human form?

The introductory verses of Chapter 16 address this theological question directly. While hailing Baba as the 'Stainless' (Niranjana), 'Imperishable' (Avyaya), and 'One beyond attributes' (Gunatita), the text asserts that he took a physical body for a specific, compassionate purpose. As mentioned in the chapter, this 'King of Yogis' assumed a human form purely 'for the sake of helping others, to uplift the poor and lowly.' This highlights that the Sadguru's incarnation is an act of grace, intended to guide and elevate humanity from worldly suffering.
