What is the significance of London in Sai Baba's teachings, and were any devotees sent there?

The provided source material does not contain any mention of London or any instructions from Sai Baba for devotees to travel there. Instead, the focus of the narrative in Chapter 18 is on Baba's methods of spiritual instruction within Shirdi. It describes how he would direct devotees to listen to sacred Hindu texts, such as the Jnaneshwari and Nath Bhagawat, which were read daily by Bapusaheb Jog in Sathe's Wada. Baba's grace extended to devotees whether they were near him or in a distant land, but the text offers no specifics about locations like London, concentrating instead on his spiritual influence and the readings in Shirdi.
