What does Chapter 10 reveal about Sai Baba's mysterious movements and the divine powers he possessed?

Chapter 10 reveals that Sai Baba's movements were often imperceptible, pointing to his divine powers, or Siddhis. The most prominent example is his ability to sleep on a narrow wooden plank suspended by mere rags, a feat that defied ordinary physical laws. The text explicitly states that no one ever knew when he climbed up or descended from this plank. Chapter 10 explains this by noting that with Great Siddhis residing within him, the plank was merely for name's sake. It further suggests he possessed 'Anima' (the power to become minute), allowing his movements to be as subtle and unnoticed as those of flies, insects, or ants, showcasing his complete mastery over the physical form.
