Can you explain how Sai Baba used the practice of asking for Dakshina to teach his followers about humility?

Sai Baba masterfully employed the practice of taking Dakshina as a profound lesson in humility for his followers. As detailed in Chapter 14, he made no distinction between the wealthy and the poor, asking for offerings from everyone. In a particularly powerful example of this teaching, Baba would sometimes command a great millionaire to go and beg for Dakshina from a poor person's house. By making the wealthy humble themselves in this way, he demonstrated that all are equal before him. The text explicitly states that the essence of this was that 'under the pretext of Dakshina, Baba was teaching His devotees to choose humility.'
