Can you describe Sai Baba's unusual sleeping arrangements as explained in Chapter 10?

Chapter 10 provides a detailed description of Sai Baba's unique sleeping situation. He would sleep on a narrow wooden plank that was only four cubits long and one span (approximately 9 inches) wide. This plank was not on the floor but was suspended from the rafters like a swing, tied at both ends with old rags. The chapter highlights the miraculous nature of this, noting that lamps would burn at his head and feet while he slept on this precarious setup. His movements were said to be so imperceptible that no one ever knew when he climbed onto the plank or descended from it.
