What does Chapter 10 of the Shri Sai Satcharitra describe about Sai Baba's unusual sleeping habits?

Chapter 10 provides a fascinating description of Sai Baba's unique sleeping arrangements. It details how he would sleep on a very narrow wooden plank, just four cubits long and one span wide. This plank was not placed on the floor but was instead suspended from the rafters of the mosque, hung like a swing with old rags. The chapter also mentions that lamps were kept burning at his head and feet while he slept on this precarious bed. His movements onto and off the plank were so subtle that they were imperceptible to anyone watching.
