Which devotee from Delhi was asked to listen to the scripture readings?

The provided sections of Chapter 18 do not mention any specific devotee from Delhi. The text describes a general practice where Sai Baba would send various devotees who came to meet him in the Masjid to go listen to scripture readings. As Chapter 18 explains, He would simply say, 'Get up, go to the Wada for that book,' to whomever was present. The narrative focuses on Baba's divine method of instruction and the spiritual benefit for the listeners, not their geographical origins.
