Can you describe the strange way Sai Baba used to sleep as mentioned in the text?

According to Chapter 10 of the Shri Sai Satcharitra, Sai Baba's sleeping arrangement was quite extraordinary and defied logic. He would sleep on a wooden plank that was only four cubits long and one span (about nine inches) wide. This narrow plank was suspended from the rafters of the mosque, like a swing, held up at both ends by old rags. What made it even more mysterious was that his movements were imperceptible; no one ever knew when he climbed onto the plank or when he descended from it. He would lie there with lamps burning at his head and feet, a feat that highlighted his divine powers.
