Describe the specific sequence of events that led to Sapatnekar holding Sai Baba's feet and the subsequent miracle.

After feeling deeply distressed and sleepless from Baba's constant rebukes, Sapatnekar made a firm resolution to stay in Shirdi until he received grace. Chapter 48 of the Shri Sai Satcharitra recounts that he saw an opportunity when Baba was alone on his cushion with no one else nearby. Seizing the moment, Sapatnekar approached and, with a choked heart, held Baba's feet, placing his head upon them. As he was massaging Baba's feet, Baba placed a reassuring hand on him. It was at this precise moment that a Dhangar woman arrived, sat down to rub Baba's waist, and Baba began the conversation that would reveal his omniscience to Sapatnekar.
