How did Sai Baba use his telepathic abilities to dictate the contents of the Uddhava Gita to a publisher in Mumbai?

The provided source material does not contain any information about Sai Baba telepathically dictating the Uddhava Gita to a publisher in Mumbai. The text in Chapter 18 describes a different kind of miracle. It states that even when a devotee was in a distant land, Baba was 'close within' and could assign tasks by giving them His own power. In Shirdi, He instructed Dixit and Jog to conduct daily readings of existing, divinely inspired books like the Uddhava Gita and Jnaneshwari to foster devotion, rather than authoring or dictating new versions of them.
