How was it possible for Sai Baba to sleep on a narrow plank tied with rags, and what does Chapter 10 reveal about his powers?

Chapter 10 explains that Sai Baba's ability to sleep on a fragile, narrow plank was a demonstration of his divine powers, or Siddhis. The plank itself, just four cubits long and a span wide, was tied with mere rags and could not have supported his weight conventionally. The text clarifies that the plank was 'merely for name’s sake' because Great Siddhis resided within him. Chapter 10 specifically mentions his mastery of 'Anima,' the power to become minute, suggesting his movements could be as subtle and easy as those of flies or insects, making his ascent and descent from the plank completely imperceptible to others.
