Could you describe the relationship between Nanasaheb Nimonkar and Maharaj, including how his devotion manifested in his final days?

Nanasaheb Nimonkar's faith in Maharaj grew gradually after he began visiting for darshan at his uncle's suggestion. According to Chapter 0, he spent his last three years in constant service to Maharaj, only returning home for daily rituals. Despite being over sixty, he served tirelessly, and Maharaj affectionately called him 'Kaka.' His devotion was most profound at the end of his life. During his final three days, he saw Maharaj everywhere and would address others, including his own wife, as 'Sai Baba,' insisting that Baba was within them. This illustrates that his end came in a state of constant, blissful remembrance of Maharaj.
