The text mentions Baba's movements were 'imperceptible.' What specific examples and explanations does Chapter 10 provide for this claim?

Chapter 10 provides a very specific and vivid example of Sai Baba's imperceptible movements in the context of his sleeping plank. It states that no one ever knew when He climbed up to or descended from the narrow plank that was hung from the rafters. The chapter explains this mystery by attributing it to His great Siddhis (powers). It specifically mentions the power of 'Anima,' the ability to become minute, suggesting that Baba could move with the subtlety of flies, insects, or ants, thus making his actions completely undetectable to ordinary human perception.
