What is the story about Dada Kelkar being asked to get meat, and what's its point?

The incident with Dada Kelkar is presented in chapter 38 as a lesson in faith and obedience. Dada Kelkar, an elderly and devout Brahmin, was asked by Sai Baba to go and purchase meat on Ekadashi, a day of fasting. Baba even gave him the money and instructed him to go personally. This order was a significant test for Kelkar, given his background and the sanctity of the day. The story illustrates a key principle: the ultimate offering, or "Dakshina," to a Guru is not merely wealth or material goods, but the unwavering performance of the Guru's orders. Pleasing the Guru through complete obedience is portrayed as the highest form of devotion.
