The text says Baba's movements were 'imperceptible.' How does Chapter 10 explain this phenomenon?

Chapter 10 highlights the mysterious and imperceptible nature of Sai Baba's movements, particularly in relation to his sleeping plank. Devotees never knew when he climbed up to the plank or when he descended from it. The text explains this was possible due to his divine powers, or Siddhis. Specifically, it mentions the power of 'Anima,' which is the ability to become minute. Chapter 10 suggests that Baba could easily move in the forms of flies, insects, or ants, which would make his actions unnoticeable to any observer, thus explaining how his movements remained a profound mystery.
