Who was Nanasaheb Dengle, and how is he connected to the story of Maharaj sleeping on a plank?

Nanasaheb Dengle was a significant devotee of Maharaj whose story is detailed in Chapter 0. He was the brother of Babasaheb Dengle and initially came to Maharaj because he did not have a son. After receiving Maharaj's blessing, he was blessed with a son, which greatly deepened his faith. Due to his devotion and concern for Maharaj's comfort in the dilapidated Masjid, Nanasaheb Dengle brought a thick wooden plank for him to sleep on. His intention was for Maharaj to sleep on the ground with it, but as Chapter 0 explains, Maharaj instead hung the plank from the rafters and slept there, creating a famous and miraculous episode.
