Can you provide some examples from the text of how Sai Baba miraculously intervened in the lives of his devotees?

Certainly. Chapter 29 provides beautiful examples of Baba's divine care. One story involves Raghunathrao, who was worried about his pension. Baba appeared in his wife's dream to test their faith and ultimately ensured he received a generous amount. Another tale is of Captain Hate, who had a dream of making a specific food offering to Baba. When he tried to make this happen from afar, Baba miraculously arranged for the exact, hard-to-find ingredient—valpapdi beans—to appear in Shirdi at the perfect moment, fulfilling the devotee's heartfelt wish.
