Can you describe Sai Baba's unusual sleeping plank as mentioned in Chapter 10?

Chapter 10 provides a detailed description of Sai Baba's unique sleeping arrangement. He would sleep on a wooden plank that was merely four cubits long and one span (about nine inches) wide. This narrow plank was suspended from the rafters of the mosque, hung like a swing using old rags. The chapter notes that Baba would sleep on this precarious plank, often with lamps burning at his head and feet. It emphasizes that his ability to rest on such a fragile structure was not due to its physical strength but was a testament to his great Siddhis (divine powers), making the plank's support "merely for name’s sake."
