Based on the text, can you analyze Sai Baba's practice of asking for Dakshina and the philosophy behind it?

Chapter 14 provides insight into Sai Baba's unique approach to Dakshina, or offerings. Upon meeting Ratanji, Baba immediately asked him for Dakshina, a practice He extended to all visitors, regardless of their faith. The amounts requested were not trivial; He would ask for hundreds or thousands and even instruct devotees to take a loan if necessary. The philosophy behind this was not greed, but a test of faith and detachment. Baba is quoted as saying, 'if he gives Me one quality, I give him a hundred qualities in return,' and promised to give 'bags of rupees' in return, suggesting that the act of giving to Him would be rewarded a hundredfold.
