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

Chapter 14 details how Sai Baba employed the custom of asking for Dakshina as a profound lesson in humility. He made no distinction between the rich and poor, asking for offerings from everyone. Notably, He would command even a great millionaire to go to a poor person's house to ask for Dakshina on His behalf. By having the wealthy beg from the poor, Baba was stripping away their ego and forcing them to adopt a humble heart. The source explains that the very essence of this practice was that 'under the pretext of Dakshina, Baba was teaching His devotees to choose humility.'
