Can you explain Sai Baba's instructions for the devotee who was planning a trip to London?

The provided source materials from Chapter 18 do not contain any reference to London or any devotee planning a trip there. Instead, the text focuses on Sai Baba's instructions related to spiritual practices within Shirdi. For instance, Baba is described as being deeply concerned with the welfare of his devotees, assigning them tasks to facilitate their spiritual growth. As detailed in Chapter 18, he would often send devotees who came to see him at the Masjid over to Sathe's Wada to listen to sacred readings. He also gave specific instructions, such as telling Madhavrao to collect fifteen rupees Dakshina from Shama, demonstrating his engagement with devotees' lives locally rather than their international travel.
