Can you elaborate on the purpose of Sai Baba testing Kaka Dixit by asking him to kill a goat?

The incident in Chapter 23 where Baba tests Kaka Dixit serves to illustrate a profound spiritual point. Although Baba knew Kaka was spiritually pure, described as "bavankasi" (pure gold), the test was a demonstration for others. The text notes that people often need tangible proof, much like a diamond's value is confirmed by enduring the blows of a hammer or the heat of a fire. This test was not for Baba's knowledge but to publicly display Kaka's unwavering faith and obedience. As Chapter 23 states, "Divine glory is not achieved without bearing the blows of a chisel," suggesting that such trials are necessary to reveal and solidify a devotee's spiritual greatness for all to witness.
