Can you tell me about the daily reading sessions that took place in Sathe's Wada?

Certainly. As detailed in Chapter 18, Sai Baba established a daily routine of sacred readings in Sathe’s Wada for the benefit of his devotees. He specifically assigned this task to Bapusaheb Jog. Every day after his afternoon meal, Jog would first go to the Masjid to bow at Baba's feet, receive Udi, and take explicit permission to begin. He would then proceed to the Wada to start the 'Parayana' (devotional reading) of either the 'Jnaneshwari' or the 'Nath Bhagawat', joyfully giving explanations of the meaning to the listeners. Baba actively supported this by sending many devotees who came to see him at the Masjid over to the Wada to listen to the reading.
