How does Chapter 10 explain Sai Baba's ability to sleep on a suspended plank and move without being seen?

Chapter 10 explains that Sai Baba's ability to sleep on a fragile, suspended plank and move imperceptibly was a display of his divine powers, or Siddhis. The text describes the plank as being just a span wide and tied with rags, questioning how it could possibly support his weight. The answer provided within the chapter is that his great Siddhis made it possible, with the plank being merely for name’s sake. It further elaborates that his movements were subtle due to powers like 'Anima', the ability to become minute, suggesting he could move in the forms of flies or insects, making his comings and goings completely unknown.
