I've heard Sai Baba slept on a suspended plank. What details are provided about this, specifically regarding how he got on and off it?

The introduction, as documented in Chapter 0, describes this miraculous event. Maharaj hung a wooden plank from the Masjid's rafters using old rags and would sleep on it, often with four lit lamps at the corners. While many people gathered to see this, a key point of mystery was how he ascended and descended. The text explicitly states that despite many people keeping watch, 'his climbing up and down was not seen by anyone.' This element remained a mystery, and to stop the growing crowds and distraction, Maharaj one day broke the plank.
