Chapter 10 mentions Baba's movements were imperceptible. What does the text reveal about His powers, like 'Anima', and how he could move unseen?

Chapter 10 highlights Sai Baba's imperceptible nature, particularly regarding how he got on and off his suspended sleeping plank, a feat no one ever witnessed. The text attributes this to the "Great Siddhis (powers) residing within Him." It specifically references 'Anima', which is the yogic power to become as minute as an atom. The chapter poetically suggests that just as the Master of 'Anima' can hide in a tiny particle, Baba's movements could be as subtle and easy as those of flies, insects, or ants. This implies He could alter his form or presence to move about without being detected by ordinary human senses.
