Chapter 10 mentions Baba's movements were 'imperceptible.' What does this mean, and how does the text connect it to His divine powers?

As detailed in Chapter 10, Sai Baba's movements were indeed imperceptible to others. Specifically, when He would climb up to or descend from the narrow wooden plank He slept on, no one ever knew how or when He did it. The text connects this mysterious ability to His Great Siddhis (divine powers). It uses the analogy of the Master of 'Anima' (the power to become minute) hiding in a tiny particle that pricks the eye. This suggests that Baba could move with incredible ease, perhaps by taking on the forms of flies, insects, or ants, making His actions unseen by ordinary people.
