Can you tell me the story of why Baba asked Dada Kelkar, a Brahmin, to buy meat on a fasting day?

Chapter 38 recounts a fascinating incident involving Dada Kelkar, an elderly and devout Brahmin. On Ekadashi, a day of fasting, Baba gave money to Dada Kelkar and ordered him to personally go to Korhala to fetch some meat. This order was a profound test of faith for Kelkar, who was perfect in his conduct and Vedic duties. The story illustrates a deeper spiritual principle mentioned in the chapter: that the true offering, or 'Dakshina,' to a Guru is not wealth or material goods, but the complete and unwavering performance of the Guru's order, which is the best way to please Him.
