How does the story of the Aurangabadkar's song demonstrate Sai Baba's omniscience and unconventional teaching style?

The incident with the Aurangabadkar's song powerfully demonstrates Baba's omniscience and his method of teaching without formal instruction. As recounted in Chapter 19, a devotee had a private, internal thought to focus on Rama's name. Immediately, Aurangabadkar, another devotee, began singing a song with the refrain "I do not believe in anything without Rama." The timing was so perfect that the narrator felt the compassionate Sai was watering the "sprout of his resolve" with the song. This illustrates that Sai does not need a specific place or time for teaching; it happens naturally, reflecting the inner state of the devotee's heart and confirming his all-pervasiveness.
