What does Chapter 10 reveal about Sai Baba's Siddhis, or divine powers, particularly regarding His movements and form?

Chapter 10 provides specific examples of Sai Baba's Siddhis, or divine powers. The most prominent example is His ability to sleep on a narrow plank suspended by rags, a feat attributed to His great Siddhis rather than the plank's physical integrity. The chapter highlights that His movements onto and off this plank were imperceptible. It also delves into His mastery of 'Anima,' the power to become minute, suggesting that Baba could easily hide in a tiny particle and that His movements could be as subtle as those of flies, insects, or ants. This demonstrates His ability to transcend normal physical laws and forms.
