Can you describe the specific details of the wooden plank Baba used for sleeping as mentioned in Chapter 10?

Chapter 10 offers a very specific description of the unusual plank Baba used for sleeping. It was a wooden plank measuring four cubits in length but was only one span, approximately nine inches, wide. This incredibly narrow plank was not on the floor but was hung from the rafters of the mosque, suspended at both ends by old, torn rags, functioning like a swing. The chapter notes that Baba would sleep on this precarious setup, often with lamps burning at His head and feet. The text emphasizes that His ability to use this plank was a display of His great Siddhis, as its physical properties seemed insufficient to support a person.
