How does Chapter 10 connect the idea of the Guru's divine power with Sai Baba's specific lifestyle choices?

Chapter 10 masterfully connects the abstract power of the Guru with the concrete, mysterious actions of Sai Baba. The chapter begins by declaring that a Sadguru can "strike a nail over the lines of destiny" and destroy karma for his devotees. It then provides a vivid example of Baba's extraordinary nature through the description of his sleeping plank. As described in Chapter 10, this plank was only a span wide and hung by rags, yet it supported him. This impossible feat served as a physical manifestation of His divine Siddhis, proving that a being with such power could indeed transcend ordinary limitations and, by extension, alter the fate of those who placed their faith in Him.
