Can you describe the strange sleeping arrangement of Sai Baba as detailed in Chapter 10?

According to Chapter 10, Sai Baba had a very peculiar sleeping arrangement that highlighted his divine nature. He would sleep on a wooden plank that was merely four cubits long and only one span, or about nine inches, wide. This narrow plank was not supported by a conventional frame but was instead hung from the rafters of the mosque like a swing, tied at both ends with old rags. As Chapter 10 describes, lamps would be kept burning at his head and feet while he rested on this precarious bed, demonstrating a lifestyle far beyond that of an ordinary person.
