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

According to Chapter 14, Sai Baba used the practice of requesting Dakshina (offerings) as a powerful teaching tool, primarily to instill humility in His devotees. The text explains that the essence of this practice was that "under the pretext of Dakshina, Baba was teaching His devotees to choose humility." He would accomplish this by sending even a great millionaire to go to a poor person's house to beg for the offering on His behalf. This act forced the wealthy to be humble in heart and obey His command, breaking down their pride and sense of status, demonstrating that He saw no difference between the rich and the poor.
