Could you provide details about how Sai Baba slept on the hanging plank and the reason he eventually stopped using it?

As described in the Introduction, Sai Baba's method of sleeping on the wooden plank was quite miraculous. After Nanasaheb Dengle brought the plank, Maharaj, instead of placing it on the ground, hung it from the Masjid's rafters using old rags. These rags miraculously supported the weight of both the plank and his body. While sleeping on this suspended plank, he would place four lit lamps at its four corners. This unusual sight attracted many curious people who would stand at a distance to watch. The source material from Chapter 0 states that despite many people keeping watch, no one ever witnessed Maharaj climbing up to or down from the plank. Because this spectacle became a significant distraction for the gathering crowds, Maharaj eventually broke the plank.
