Explain Sai Baba's unique practice of asking for Dakshina from his devotees as presented in the source material.

Sai Baba's practice of requesting Dakshina, or an offering, was a distinct feature of his interactions with all visitors, whether Hindu, Muslim, or Parsi. According to Chapter 14, his requests were not for small, token amounts. He would ask for varied sums, from a few rupees to hundreds, thousands, or even lakhs, and might even insist a devotee take a loan to provide it. He also promised to give back far more in return, telling devotees not to worry. This practice was not about personal enrichment, as evidenced by his command for a millionaire to sometimes seek Dakshina from a poor person's house, showing the act had a deeper, spiritual significance beyond the monetary value.
