Can you detail Sai Baba's unusual sleeping arrangements as described in Chapter 10?

According to Chapter 10, Sai Baba had a very peculiar sleeping arrangement. He would sleep on a narrow wooden plank, described as being four cubits long but only one span (approximately 9 inches) wide. This plank was not on the floor but was hung from the rafters like a swing, tied at both ends with old rags. Baba would sleep on this precarious perch, often with lamps burning at his head and feet. The chapter highlights the mysterious nature of this, questioning how such a setup could support his weight, attributing it to his great Siddhis or powers.
