Can you detail the story of Baba's visit to Delhi as described in Chapter 18?

Based on the provided excerpts, there is no mention of Sai Baba visiting Delhi or telling any stories about such a trip. The content of Chapter 18 focuses entirely on Baba's methods for instructing devotees in Shirdi, primarily through the organized reading of sacred scriptures like the Nath Bhagawat and Jnaneshwari. As described in Chapter 18, Baba would often send devotees to Sathe's Wada to listen to Bapusaheb Jog read these books, sometimes confirming a story He had just told them through the text.
