How does Chapter 10 describe Sai Baba's mysterious sleeping arrangements and his divine powers?

Chapter 10 details Sai Baba's extraordinary sleeping habits, which demonstrated his divine nature. He would sleep on a narrow wooden plank, merely four cubits long and one span wide, which was suspended from the rafters by old rags, like a swing. What made this truly mysterious was that his movements were imperceptible; no one ever saw when he got onto the plank or when he descended. The text explains this was possible due to the Great Siddhis (powers) residing within him, suggesting the plank was just for show. This demonstrates that Baba's physical form was not bound by ordinary limitations.
