Can you describe Sai Baba's specific sleeping arrangements as detailed in Chapter 10?

According to Chapter 10, Sai Baba's sleeping arrangements were quite extraordinary and mysterious. He would sleep on a narrow wooden plank, described as being four cubits long but only one span wide, which is approximately nine inches. This plank was not on the floor but was hung from the rafters like a swing, tied at both ends with old rags. The chapter highlights that Baba would sleep on this precarious perch, often with lamps burning at his head and feet. What made this even more remarkable, as Chapter 10 notes, was that his movements were imperceptible; no one ever saw him climb up onto the plank or get down from it.
