Why did Sai Baba take on a physical body, as explained in Chapter 16?

Chapter 16 describes Sai Baba as the 'King of Yogis,' who is stainless, imperishable, and beyond attributes ('Gunatita'). Despite this transcendent nature, the text explicitly states the compassionate reason for his incarnation. It says, 'You have taken this body for the sake of helping others, to uplift the poor and lowly.' This key passage from Chapter 16 emphasizes that the purpose of His physical manifestation was not for His own sake, but purely as a selfless act of grace to guide and elevate humanity, particularly those who are spiritually and materially impoverished.
