Describe the exact method Sai Baba employed to return Hari Kanoba's lost property and the conditions that had to be met for its retrieval.

Sai Baba employed a unique and miraculous method to return Hari Kanoba's lost shoes. As narrated in Chapter 49, after Hari Kanoba discovered his shoes were missing, Baba located them and gave them to a Maratha boy. The boy was instructed to carry the shoes on the end of a stick, like a banner. The return was conditional upon fulfilling Baba's specific instructions. The first condition was that the boy had to go around calling out, 'Son of Hari, gold-bordered turban.' The second condition, as Chapter 49 clarifies, was that the boy would only hand over the shoes to the person who could prove they met both criteria. Hari Kanoba had to identify himself as the 'son of Hari' and show his gold-bordered turban before the boy was convinced and relinquished the footwear.
