Chapter 10 mentions Baba's movements were 'imperceptible.' How does the text explain this mysterious ability?

Chapter 10 explains Sai Baba's imperceptible movements by attributing them to his divine powers, or Siddhis. The primary example given is his ability to get on and off a narrow wooden plank suspended from the ceiling without anyone ever witnessing the act. The text poses the question of how such a flimsy setup could support his weight and answers that his Great Siddhis made it possible. It specifically alludes to the power of 'Anima,' which is the yogic siddhi of becoming minutely small. The chapter suggests that Baba could easily move in the forms of flies, insects, or ants, thus rendering his movements undetectable to ordinary perception.
