What's the story behind Sai Baba asking Dada Kelkar, a devout Brahmin, to buy meat on a fasting day?

Chapter 38 recounts a fascinating incident intended to teach a lesson about faith. On Ekadashi, a fasting day, Sai Baba gave money to Dada Kelkar and ordered him to personally go and get meat. This was a startling order, as Dada Kelkar was an elderly, devout Brahmin with great respect for Vedic duties and perfect in his conduct. The text describes the order as a "novelty" to him. This act was not about the meat itself, but a profound test of Dada Kelkar's obedience and faith. The narrative suggests that a disciple who doubts a Guru's command, questioning what is edible or inedible, suffers a spiritual downfall. The story illustrates the principle of surrendering one's personal convictions to the Guru's wisdom.
