I read that Nanasaheb Dengle provided the plank Baba slept on. What was his initial connection to Maharaj?

Nanasaheb Dengle's deep connection to Maharaj began with a personal miracle that transformed his life. As recounted in Chapter 0, it was Nanasaheb himself who was without a son. Despite even taking a second wife, he remained childless. It was on the advice of his brother, Babasaheb Dengle, that Nanasaheb went for Maharaj's darshan. During this visit, Maharaj blessed him with the promise of a son, and in due course, this divine blessing came to pass. This profound event solidified Nanasaheb's faith, and he became a frequent visitor to Shirdi. His later act of bringing a wooden plank for Maharaj to sleep on was a beautiful expression of the immense gratitude and devotion that grew from this initial, life-changing blessing.
