Can you explain the incident where Baba asked Dada Kelkar, a Brahmin, to buy meat? What was the spiritual significance of this command?

Chapter 38 recounts an incident where Sai Baba tested the faith of a devout Brahmin devotee, Ganesh Damodar Kelkar, known as Dada. On Ekadashi, a fasting day, Baba ordered Dada Kelkar to personally go and purchase meat, even providing the money for it. For a Brahmin who was perfect in his conduct and devoted to Vedic duties, this was a novel and challenging command. The spiritual significance lies in the principle of absolute obedience to the Guru. The text explains that the highest form of 'Dakshina' (offering) is not wealth or material goods, but the faithful performance of the Guru's order. This event was a lesson to show that a disciple's faith should transcend personal conditioning and doubt.
