Who was Nanasaheb Dengle and what was his relationship to the hanging plank in the Masjid?

Nanasaheb Dengle was a devotee whose faith in Maharaj grew after he was blessed with a son. According to Chapter 0, Nanasaheb observed that the Masjid where Maharaj slept was completely dilapidated. With the intention that Maharaj should not have to sleep on the bare ground, he brought a thick wooden plank for him to use. This plank is the same one that Maharaj, in his unique way, chose to hang from the rafters with old rags to sleep on, an act that astonished many followers.
