Can you elaborate on Sai Baba's activities on the alternate nights He spent at the Chavadi?

Chapter 22 describes the special routine on the alternate nights when Sai Baba would go from the Masjid to stay in the Chavadi. On these nights, Amir Shakkar, who was residing there, would have a unique experience. After the usual worship and Aarti ceremonies were concluded, the devotees would return to their homes. This left Baba and Amir in the Chavadi, separated only by a nominal curtain and a plank door. In the quiet that followed, with calm minds, they would talk to each other, enjoying a firm companionship that was a rare and fortunate experience.
