Can you describe the unusual place where Sai Baba used to sleep? What was so mysterious about it?

Chapter 10 provides a fascinating description of Sai Baba's unique sleeping arrangement. He would rest on a very narrow wooden plank, described as being only four cubits long and a mere one span (approximately 9 inches) wide. This plank was not on the floor but was suspended from the rafters of the mosque like a swing, tied at both ends with old rags. The mystery, as detailed in this chapter, was that his movements were completely imperceptible; no one ever witnessed him climbing up onto the plank or descending from it. This miraculous feat was attributed to his great Siddhis, or divine powers.
