Can you describe Sai Baba's unusual sleeping arrangement as mentioned in the Satcharitra?

Chapter 10 provides a fascinating account of Sai Baba's sleeping arrangements. He would sleep on a very narrow wooden plank, described as being four cubits long and only one span (approximately 9 inches) wide. This plank was not supported by a frame but was hung from the ceiling rafters with old rags, functioning like a swing. As detailed in Chapter 10, what made this even more mysterious was that his movements were imperceptible; no one ever saw when he climbed onto the plank or when he got down from it, despite lamps burning at his head and feet through the night.
