Can you explain the story of Sai Baba and the wooden plank he used for sleeping?

The story of the wooden plank is a notable event from Maharaj's early days in the dilapidated Masjid. As detailed in the Introduction, a devotee named Nanasaheb Dengle provided a thick wooden plank for Maharaj to sleep on, intending for him to avoid the dusty ground. However, Maharaj used it in a unique and miraculous way. He hung the plank from the rafters using old rags and began sleeping on it. These rags seemed too weak to support even the plank, yet by Maharaj's power, they held both the plank and his body. He would also place four lit lamps at the corners while sleeping. This spectacle drew many curious onlookers, but no one ever saw him ascend or descend from the plank. Eventually, as mentioned in Chapter 0, Maharaj broke the plank to remove this distraction for the people.
