How does the provided text illustrate Sai Baba's role as a 'puppeteer' in guiding his devotees?

The text in Chapter 19 vividly illustrates this concept by stating, "We are all merely puppets; the puppeteer is Mother Sai." This is demonstrated through the narrator's experience. Just as he resolved to regulate his mind with Rama's name, a devotee named Aurangabadkar began singing a song about complete devotion to Rama. The narrator realizes this couldn't be a coincidence, as no one knew his inner thoughts. He concludes that Baba, the puppeteer, pulls the strings to make inspiration happen, thereby handing over a good practice and providing direct proof of his guidance without speaking a word himself.
