How could a plank and Sai Baba's body be supported by mere rags, and what eventually happened to it?

The source material presents this as a demonstration of Maharaj's divine power. Chapter 0 explains that the old rags used to suspend the plank from the rafters were not strong enough to even bear the weight of the plank alone. Yet, due to Maharaj's power, they supported both the plank and his body. This spectacle attracted large crowds, and because it became a distraction, Maharaj took action. The text states, "Since many people started gathering to see this, Maharaj one day broke the plank to remove this distraction," thus putting an end to the phenomenon.
