Based on the source, can you provide an example of Sai Baba's teaching methods?

Chapter 19 provides a vivid example of Sai Baba's direct and impactful teaching style. The text notes that Baba, being omniscient, gives instruction at precisely the right time. In the story, a devotee had been engaging in slander. To teach him a lesson, Baba waited until he was with a group of followers and pointed to a village sow eating excrement. He then remarked, "See what taste that tongue has; it picks through people's excrement; it rages against brothers and kin and satisfies its own desire as it pleases." This visceral comparison was aimed directly at the devotee, who was "deeply stung in his heart" as he remembered his morning's gossip. This incident shows how Baba used real-world, often shocking, imagery to make devotees confront their own faults.
