Can you describe the strange plank Sai Baba used to sleep on, as detailed in Chapter 10? It sounds impossible.

According to Chapter 10, Sai Baba's sleeping arrangement was indeed extraordinary. He slept on a narrow wooden plank that was only four cubits long and a mere one span (about 9 inches) wide. This plank was not supported by a frame but was hung from the mosque's rafters like a swing, tied at both ends with old rags. Adding to the mystery, Baba would keep lamps burning on the plank at his head and feet while he slept. The text notes that his movements of getting onto and off this precarious plank were completely imperceptible, as no one ever witnessed him do it.
