How does Chapter 10 explain Sai Baba's ability to sleep on a narrow, suspended plank without anyone seeing him get on or off?

Chapter 10 explains this mysterious feat by attributing it to Sai Baba's divine powers, or Siddhis. The text posits that the flimsy plank, tied with rags, could not have possibly supported his weight on its own and was therefore "merely for name’s sake." It was the Great Siddhis residing within Him that made it possible. The chapter further elaborates by referencing the power of 'Anima,' the ability to become minute, suggesting Baba could move with the subtlety of flies or ants, which is why his movements were imperceptible.
