What specific sacred texts was Shama assigned to read daily by Sai Baba, and where did these readings take place?

The provided source material does not indicate that Shama was assigned any daily reading duties. Chapter 18 clearly identifies Sakharam Hari Jog (Bapusaheb Jog) as the devotee tasked with reading sacred texts like the Jnaneshwari and Nath Bhagawat daily in Sathe's Wada. Shama is mentioned in a different context within the same chapter, where Baba sends a message via Madhavrao to collect fifteen rupees Dakshina from him. However, the responsibility for the daily scriptural readings, or Parayana, is explicitly attributed to Jog, not Shama.
