How did Sai Baba use the practice of asking for Dakshina to teach his devotees about humility?

The source text explains that Sai Baba used the practice of Dakshina as a pretext to teach his followers about humility. As described in Chapter 14, Baba would even command a great millionaire to go to a poor person's house and beg for Dakshina on His behalf. The act of begging, especially for someone wealthy, was a direct lesson in choosing humility. This practice demonstrated that in Sai's eyes, there was no difference between a great wealthy person and a beggar, as He did not see one as less or more than another.
