How does Chapter 10 describe Sai Baba's sleeping arrangements, and what was so miraculous about them?

According to Chapter 10, Sai Baba's sleeping arrangement was extraordinary and defied normal explanation. He would sleep on a narrow wooden plank, described as being only four cubits long and one span (about nine inches) wide. This plank was not supported by a solid structure but was hung from the rafters of the mosque like a swing, tied at both ends with old rags. Miraculously, Baba would sleep on this precarious perch, often with lamps burning at his head and feet. Chapter 10 emphasizes that his movements were imperceptible; no one ever saw when he climbed onto the plank or when he descended from it, highlighting his divine powers.
