Can you tell me about Sai Baba's strange sleeping plank as described in Chapter 10?

Chapter 10 provides a fascinating description of Sai Baba's unusual sleeping arrangement. He would sleep on a narrow wooden plank that was just four cubits long and a mere span (about 9 inches) wide. This plank was not placed on the floor but was hung from the rafters of the mosque like a swing, suspended at both ends by old rags. The text highlights the miraculous nature of this, questioning how such a flimsy setup could support Baba's weight. Lamps would burn at his head and feet while he slept on this precarious perch, adding to the mystique of the scene described in this chapter.
