How did Sai Baba use the specific details of a person's name and clothing to prove his all-knowing nature in the case of Hari Kanoba's lost shoes?

In the incident with Hari Kanoba, Sai Baba's omniscience was demonstrated through his use of highly specific, personal details that he could not have known through ordinary means. As Chapter 49 recounts, after Hari Kanoba lost his shoes, Baba dispatched a boy to return them. The instructions were not general; Baba told the boy to cry out for the 'Son of Hari' who wore a 'gold-bordered turban.' This combined a play on Hari Kanoba's name ('Son of Hari') with a specific detail of his attire. The boy was under strict orders to only give the shoes to the person who matched both signs. By making Hari Kanoba prove his identity against these two very specific markers, Baba removed all doubt about the source of this knowledge, proving his divine insight and turning a skeptic into a devotee.
