Can you describe Sai Baba's sleeping arrangements as detailed in Chapter 10 and explain their significance?

As detailed in Chapter 10, Sai Baba's sleeping arrangement was highly unusual and mysterious. He slept on a wooden plank that was merely four cubits long and one span (about nine inches) wide. This narrow plank was suspended from the rafters of the mosque, like a swing, tied at both ends with old rags. The significance of this, as the chapter points out, was to demonstrate His divine powers, or Siddhis. The text questions how such a flimsy setup could support Baba's weight and emphasizes that his movements—climbing up and down—were imperceptible to all, suggesting the plank was merely for "name's sake" and a display of His extraordinary capabilities.
