How did Sai Baba use the task of buying meat to test the faith of his devotee, Dada Kelkar?

Sai Baba taught profound spiritual lessons through seemingly unusual orders. Chapter 38 recounts an incident where Baba tested Ganesh Damodar Kelkar, a devout Brahmin who was perfect in his conduct and Vedic duties. On Ekadashi, a fasting day, Baba ordered Dada Kelkar to personally go and fetch some meat, even providing the money for it. This command was a novelty and a significant test for a Brahmin, especially on a holy day. The underlying lesson, as the chapter explains, is that the truest form of 'Dakshina' or offering to a Guru is not merely wealth or items, but the complete and unwavering performance of the Guru's order, which is the ultimate way to please the Guru.
