Chapter 10 mentions that Baba's movements were 'imperceptible.' What examples are given, and how is this quality explained?

The primary example of Sai Baba's imperceptible nature in Chapter 10 relates to his sleeping plank. He rested on a narrow board hung from the ceiling by rags, yet the text emphasizes that "when He climbed up or down, no one ever knew." This mysterious ability is explained as a manifestation of his Great Siddhis (divine powers). The chapter specifically references 'Anima,' the yogic power to become minute, suggesting Baba could make his movements as subtle and unnoticeable as those of "flies, insects, or ants." This illustrates that his physical presence and actions were not bound by ordinary limitations.
