Why did Sai Baba tell the author he couldn't go to London to write the book?

The provided source text does not contain any mention of London or any travel restrictions placed on the author by Sai Baba. Instead, the narrative in Chapter 2 focuses on the divine permission and encouragement given for the book's creation. Sai Baba instructs the author, "Certainly keep a record; whether at home or elsewhere, keep remembering it repeatedly." This indicates freedom of location. The core instruction was not about where to write, but how. Sai Baba emphasized that He himself would be the true author, stating, "I myself shall write my own story!" The author was simply to act as a "pretext" by dissolving his ego and surrendering at Sai's feet, which was the condition for receiving full assistance.
