How does Sai Baba impart wisdom and guidance without using direct verbal instruction?

According to Chapter 19, Sai Baba's teaching methods are often subtle and pervasive. He does not require a specific place or time for his lessons; they happen naturally while sitting, standing, or walking. The text gives an example where a devotee's inner resolve to chant Rama's name was confirmed and strengthened when another devotee, Aurangabadkar, coincidentally began singing a song about Rama. This illustrates how Baba, as the puppeteer, pulls the strings to orchestrate events that provide instruction, showing that he knows the devotee's inner heart and provides direct proof of his guidance.
