I'm looking for the part where Baba talks about his experiences in Delhi. Can you find it for me in the source material?

While you're asking about Delhi, the provided texts from Chapter 18 do not mention that city or any of Baba's experiences there. The focus of this chapter is on Baba's unique methods of spiritual instruction in Shirdi. For instance, Chapter 18 explains that Baba assigned Bapusaheb Jog the task of reading sacred books like Jnaneshwari and Nath Bhagawat daily in Sathe's Wada. Jog would first seek Baba's permission and Udi before commencing the reading, and Baba would then send other devotees who came for his darshan to go listen, ensuring the welfare of his followers through this practice.
