Who were some of the early devotees mentioned in the introduction, and what were their initial interactions with Maharaj?

The Introduction, or Chapter 0, introduces several key early devotees. One was Annasaheb Gadgil, a government official's chitnis, who came for darshan and whose faith grew until he became a full devotee. Another was Nanasaheb Dengle, who, out of concern for Maharaj's comfort in the dusty, dilapidated Masjid, brought a thick wooden plank for him to sleep on. A third devotee mentioned is Gopalrao Gund, a Revenue Circle Inspector from Kopargaon. He had three wives but no son, and after being blessed with a son by Maharaj's grace, he became a total devotee and tried to rebuild the Masjid.
