Chapter 10 says Baba's movements were 'imperceptible.' How does the text explain this? Does it have to do with his powers?

Chapter 10 explains that Sai Baba's imperceptible movements were a direct result of His great Siddhis, or divine powers. The primary example given is how he got onto and off the narrow plank suspended by rags, a feat no one ever saw. The text posits that the plank's ability to support him was due to these powers. Specifically, the chapter mentions the Siddhi of 'Anima,' the power to become minute. It suggests that Baba could easily move about in the forms of flies, insects, or ants, which would make his actions unnoticeable to human eyes.
