Tell me everything the text says about the plank Maharaj slept on, including any details about lighting.

The provided information in Chapter 0 explains that because the Masjid was dilapidated, a devotee named Nanasaheb Dengle brought Maharaj a thick wooden plank to sleep on. Rather than placing it on the dusty ground, Maharaj hung it from the rafters using old rags and slept on it. The rags seemed too weak but miraculously held the weight of both the plank and Maharaj. While sleeping on this suspended plank, he would place four lit lamps at the four corners. This sight attracted many curious people, but no one ever saw how he got onto or down from the plank. Eventually, Maharaj broke the plank because the crowds gathering to see it had become a distraction.
